Motivation - -The data-loading agent stalls on large tables. Real symptom, verbatim from a session: - -> Found the three requested Kusto tables under SampleMetrics. SQLServerLocation is tiny and safe to load fully. The two metrics tables are very large; **their column metadata is not synced, so I cannot safely add column filters or aggregations yet.** This plan loads only the platform-limited subset for exploration, not the full tables. - -The agent did the right thing given what it can see — but what it can see is a **stale, column-less cache snapshot**. It has no way to look at the live source, so it can't build the filter/aggregation that would let a big table load safely. We route oversized tables into the chat precisely so the agent can narrow them down (design 25 / the size-routing work), and then the agent has no tool to actually do it. - -The fix we want is **not** per-connector prompt tuning or one-off Kusto hacks. We want the agent to have **generic, connector-level tooling to interrogate any source**, so: - -- A new loader gets useful agent behavior "for free" from base-class defaults. -- No loader needs bespoke agent glue or instance-specific tuning. -- The agent reasons about *any* source (SQL, Kusto, Mongo, Superset, blob, …) through one stable vocabulary. - -This doc proposes what that interface looks like. - ---- - -## 2. Where we are today - -### 2.1 The loader interface already has live read methods - -`ExternalDataLoader` is richer than the agent uses. Existing (mostly live) methods: - -| Method | Live? | Returns | -|---|---|---| -| `list_tables(filter)` / `ls(path, filter)` | live | table enumeration | -| `catalog_hierarchy()` / `effective_hierarchy()` / `pinned_scope()` | pure | navigation shape | -| `get_metadata(path)` | **live** | columns, types, `row_count`, `sample_rows` | -| `get_column_types(source_table)` | **live** | source column types (widget hints) | -| `get_column_values(source_table, column, keyword, limit, offset)` | **live** | distinct values (default: empty) | -| `fetch_data_as_arrow(source_table, import_options)` | **live** | bounded rows w/ `columns`, `filters`, `source_filters`, `sort`, `size` | - -### 2.2 The agent can't reach any of them - -The three discovery tools are **cache-only** (design 32 made this an explicit non-goal: "No live connector calls during browse"): - -- `list_data` / `find_data` → read `catalog_cache/.json`. -- `describe_data` → [`handle_read_catalog_metadata`](../py-src/data_formulator/agents/context.py) just loads the cache entry and formats it. It never calls `get_metadata`. - -`execute_python` runs in a sandbox with **no connector access** (pandas/duckdb over `scratch/` files only). So the agent's only live interaction with a source is indirect and after-the-fact. - -### 2.3 Why the cache is column-less for the failing case - -Cluster-wide Kusto browse (no pinned DB) runs `list_tables(fetch_columns=False)` on purpose — the bulk `.show database schema as json` per database across a whole cluster times out. So cluster-wide cache entries carry `row_count` + description but **no columns**. `describe_data` faithfully reports "not synced". This is the correct perf tradeoff for *browsing*; it's the wrong data for *the agent deciding how to filter*. - -### 2.4 The load boundary: no raw queries — on purpose - -`fetch_data_as_arrow` is deliberately constrained: - -> Only source_table is supported (no raw query strings) to avoid security and dialect diversity issues across loaders. - -This is a core principle we should preserve. **"Give the agent direct DB access" cannot mean "let the LLM emit raw SQL/KQL".** It must mean "give the agent a rich, structured, read-only capability vocabulary that each loader compiles to its own dialect." - ---- - -## 3. Design principles - -1. **Structured, not raw.** The agent expresses intent as structured operations (filter, project, group, aggregate, count, distinct, profile). Loaders compile to SQL/KQL/pipeline. No LLM-authored query text ever reaches a driver. -2. **Connector-level & generic.** Capabilities live on `ExternalDataLoader`. The agent never special-cases a source. One tool surface for all loaders. -3. **Native-first execution; shared building blocks, not a lowest-common-denominator default.** Each loader runs a probe the way its backend does it best — DB systems compile the query to their dialect and push it down to the source engine; file/object systems read-and-compute in an embedded engine (DuckDB) over the actual files. The base class supplies *reusable strategy building blocks* (a shared SQL compiler, a DuckDB read-and-compute helper) so a loader **picks a strategy** rather than hand-rolling one, and any loader in a known family (SQL, file) is useful for free. A bounded-sample fallback exists for the rare loader that can do neither, but it is explicit and advertises `approximate` — it is **never** the silent default. We do **not** ship the old "pull a local copy of N rows and re-aggregate a sample" behaviour as the universal path: it is approximate for large tables and wastes bandwidth pulling raw rows a real backend could have aggregated itself. -4. **Read-only & bounded.** Every capability is read-only, row/time/byte-capped, and time-limited. Reuse the `notruncation`-on-bounded-fetch pattern; never unbounded. -5. **Exactness is self-describing.** Every probe result carries an `exact` flag, so the agent (and UI) knows whether a number is source-exact or a bounded-sample approximation without a separate capability-negotiation step. -6. **Stay agentic — no cache write-back.** Probe/describe results live in the agent's conversation context and drive the current turn's reasoning; they are **not** persisted back into `catalog_cache`. The cache stays owned by the browse/sync path (design 14/32); the agent just reads live when it needs more than the cache holds. This keeps the two concerns cleanly separated and avoids merge/staleness conflicts. - ---- - -## 4. Proposed interface: `describe` + `probe` - -Two capabilities on `ExternalDataLoader`, both keyed by catalog `path` (the same list `get_metadata` already takes): - -- **`describe(path)`** — schema/metadata (columns, types, `row_count`, a small `sample_rows`). Not a data query; it's the Phase-1 unblocker. -- **`probe(path, query)`** — a single bounded read expressed as a restricted **single-table Select–Project–Aggregate query** (SPJ *minus the join* — see §4.2). One function, one compiler per loader, covering count / distinct / sample / aggregate as degenerate shapes of the same object. - -### 4.1 `describe(path)` -Live schema + sample. Thin wrapper over `get_metadata(path)` returning columns, types, `row_count`, and a small `sample_rows`. When the cache lacks columns (the reported failure), the agent calls this and gets the real schema back. - -### 4.2 `probe(path, query)` — the SPJQ query object -A structured, read-only query over **one table**. It speaks the source-agnostic filter vocabulary from design 13 and expresses select (σ), project (π), and aggregate (γ) — deliberately **no join**. That "single-table only" restraint is what keeps it compilable across every backend and stops it degenerating into a raw-query hole. - -```jsonc -{ - "path": ["db", "table"], // ONE table — no joins, no subqueries - "filters": [{"column": "...", "op": "EQ|NEQ|GT|GTE|LT|LTE|IN|ILIKE|BETWEEN|IS_NULL", "value": ...}], // σ - "columns": ["colA", "colB"], // π (projection; omit = all) - "group_by": ["region"], // γ keys - "aggregates": [{"op": "count|count_distinct|sum|avg|min|max", "column": "...", "as": "..."}], // γ metrics - "order_by": [{"column": "...", "dir": "asc|desc"}], - "limit": 100 // bounded, hard-capped -} -``` - -Everything the agent needs is a degenerate shape of this one object: - -| Intent | Query shape | -|---|---| -| **sample** rows | no `group_by`, no `aggregates`, `limit=N` | -| **count** | `aggregates=[{op:count}]`, no `group_by` | -| **distinct values** (+ frequency) | `group_by=[c]`, `aggregates=[{op:count}]`, `order_by` desc | -| **profile / aggregate** | `group_by=[region]`, `aggregates=[sum(x), min(ts), max(ts)]` | -| **date range** | `aggregates=[{op:min,column:ts}, {op:max,column:ts}]` | - -The **same** SPJQ object compiles to each backend's native form; **§5** details the per-backend execution strategies (native pushdown for DBs, read-and-compute for files, an explicit sample fallback). - -Result payload: `{rows, columns, row_count?, exact: bool, compiled_note?}` — `exact=false` flags the rare sampled/approximate answer (Strategy C, §5.3). - -`limit` is always **hard-capped server-side** (e.g. `min(limit, MAX_PROBE_ROWS)`) — not for correctness but to protect the agent's context window. We deliberately never return a large table for the LLM to parse, because those rows become input tokens on the next turn. The result message **always** states the cap so the agent knows it is looking at a capped preview, e.g. *"showing 50 of N rows (capped at 50 — use aggregate shapes or the load plan for the full table)"*. When `group_by`/`aggregates` reduce the result below the cap the note simply confirms the full grouped result fit; when the cap trims raw rows it also sets `exact=false`. - ---- - -## 5. Execution strategies — native-first, per backend - -A probe is **always compiled and executed against the backend that owns the data** — never by pulling a "local copy" of raw rows back to the app and re-aggregating a sample. `describe` stays a thin live wrapper over `get_metadata` (native `information_schema` / `.show schema` where a loader overrides it). `probe` runs with one of three strategies; the first two are exact and are the expected path, the third is an explicit, advertised fallback. - -### 5.1 Strategy A — Native pushdown (DB systems) - -Postgres, MySQL, MSSQL, BigQuery, Athena, **Kusto**, Mongo. The loader compiles the SPJQ object to its own dialect and executes it **on the source engine**: - -- SQL family → `SELECT … WHERE … GROUP BY … ORDER BY … LIMIT` (shared compiler, dialect-specific quoting; alongside the existing `build_*_where_clause*` helpers). -- Kusto → `T | where … | summarize … by … | order by … | take …`. -- Mongo → single-collection pipeline `$match / $group / $sort / $limit`. - -The source filters/groups/aggregates over the **whole** table using its own indexes and returns only the small result. Always `exact=true`. This is the path that fixes the large-Kusto-table motivation: a `summarize … by …` over the full table instead of a sample of the first N rows. - -### 5.2 Strategy B — Read-and-compute (file / object systems) - -Local folder, S3/blob, and other file-backed sources (parquet/csv/json). There's no query engine on the source, so "native" here means **hand the file(s) to an embedded analytical engine (DuckDB) and run the compiled SQL there** — letting DuckDB scan the file directly (`read_parquet('…')` / `read_csv_auto('…')`) with predicate & projection pushdown into the scan. Reading the file *is* the native operation for these sources, so this is **exact**, not a sample. Because DuckDB speaks SQL, the **same compiler as Strategy A** produces the query — only the `FROM` target differs (`read_parquet('…')` vs. a table name). This is the preferred implementation for file sources: DuckDB is faster and more correct than hand-rolling scans/aggregation in Python. - -### 5.3 Strategy C — Bounded-sample (explicit fallback only) - -For the rare loader that can neither push down nor cheaply read-and-compute (e.g. a thin API loader exposing only `fetch_data_as_arrow`), the base class offers `_probe_via_sample`: fetch a bounded set of rows and compute the SPJQ over that sample in DuckDB. This is `exact=false`, and the loader must **opt in** by overriding `probe` to call it. It is **not** a silent default — we add a proper native strategy in preference to leaning on it. The `exact` flag travels back to the agent so it can phrase a sampled number honestly. - -### 5.4 Shared building blocks - -So "each backend instantiates the probe arguments to best do computation" — but they don't each reinvent it: - -- **SQL compiler** (one place): SPJQ → SQL with parameterized/escaped values and dialect quoting. Reused by every SQL DB (Strategy A) *and* the DuckDB read-and-compute path (Strategy B). This is the big reuse — one compiler, two families. -- **DuckDB engine helper**: point DuckDB at a loader's file(s), run the shared-compiled SQL, return Arrow. Serves the whole file/object family. -- **Kusto & Mongo** bring their own compilers (KQL / aggregation pipeline) but reuse the same SPJQ object and result payload. - -A new SQL or file loader gets a working, exact probe by wiring into the matching mixin; only a genuinely new *kind* of backend needs a new compiler. - -### 5.5 No separate capability negotiation - -Earlier drafts advertised an `agent_capabilities()` map (`pushdown`/`approximate`/`unavailable`). That is redundant: the probe result already carries `exact` (true for Strategy A/B, false for the Strategy C sample), and a loader that hasn't opted into any strategy returns an `{error}` from the base `probe`. The agent reads the `exact` flag to caveat approximate numbers and treats an error as "probe unavailable, fall back to describe / the load plan" — no extra negotiation method to keep in sync. `probe` stays a concrete base method (not `@abstractmethod`) so third-party plugin loaders that predate it keep working; the default simply reports the source unsupported. - ---- - -## 6. Agent integration - -1. **Live loader resolution inside a tool call.** The agent stream runs inside the Flask request context, so `DataConnector._get_identity()` + `load_connectors(identity)` + the registry lookup (mirroring [`_resolve_connector_with_key`](../py-src/data_formulator/data_connector.py)) can turn `source_id → live loader` mid-turn. Factor a small helper so the agent/context layer isn't cache-only anymore. -2. **Two tools** thin-wrap the capabilities: `describe_data` (gains a live fallback — auto when the cached entry has no columns, capped to table nodes) and `probe_data(path, query)` (the single SPJQ probe). One query tool means fewer ways for the LLM to mis-select. Both the tool description and every result message make the row cap explicit — `probe_data` returns *at most N rows* and exists for inspection/reasoning, not bulk loading — so the agent understands it will never get a huge table dumped into its context and routes full-data needs through the load plan instead. -3. **Stay agentic — results are in-context only.** `describe`/`probe` results feed the agent's reasoning for the current turn; we do **not** write them back into `catalog_cache`. If a later turn needs fresh schema again it simply re-describes (cheap, bounded, budget-capped). The cache remains owned by the browse/sync path, so there's no merge-with-`sync_catalog_metadata` problem to solve. -4. **Prompt update.** Teach the probe→plan loop: `describe_data` for schema, `probe_data` (count / distinct / aggregate shapes) to size the slice and pick real filter values, then `propose_load_plan`. Reinforce "never guess columns/values — probe first" (the prompt already says this for the cache path). -5. **Shared query object with the load path.** `probe` *without* `group_by`/`aggregates` is the same select-project-limit shape `fetch_data_as_arrow` / `ingest_to_workspace` already consume via `import_options`. Converging them on one query object means the agent probes and loads with the *same* structure, and there's one compiler per loader serving both — a net simplification, not just a new tool. - ---- - -## 7. Security & guardrails - -- **Read-only.** No DDL/DML/writes; capabilities compile only to read queries. The raw-query ban stays. -- **Bounded everything.** Row caps, byte caps (`notruncation` only on a bounded shape), and per-call timeouts. Reuse `MAX_IMPORT_ROWS` conventions. -- **Per-turn probe budget.** Cap probe calls per turn to avoid a chatty agent hammering the source; return a "budget exhausted" signal. -- **Serialize non-parallel-safe clients.** Kusto's client mutates `self.kusto_database` per query — probes must serialize like batch import does. -- **Identity scoping.** Loader resolution goes through the same per-identity registry as imports; no cross-user leakage. -- **Injection surface.** Because the agent supplies *values*, not query text, values flow through the existing parameterized/escaped builders. Column/table identifiers validated against the (freshly probed) schema, not free-form. - ---- - -## 8. Phasing - -- **Phase 1 (unblock):** live `describe_data` fallback (`get_metadata`) — auto-fires when a table node's cached columns are missing. Fixes the reported failure with the smallest surface. Low risk, high value. -- **Phase 2 (probe — exact strategies first):** ship `probe_data` with the two exact strategies — the shared SQL compiler + Strategy A pushdown for the SQL family, and Strategy B read-and-compute (DuckDB over the files) for file/object sources. These cover the common cases correctly; no approximate default. -- **Phase 3 (remaining DB natives + fallback + prompt loop):** Kusto/Mongo `probe` compilers (KQL / pipeline) for exact source-side aggregation; the explicit bounded-sample fallback (Strategy C) for any loader that can do neither; probe→plan prompt loop. -- **Phase 4 (polish):** UI reuse of the probe `exact` flag for smart filter widgets; profile caching; approximate→exact upgrade hints. - ---- - -## 9. Open questions - -1. ~~**Tool granularity for the LLM:** one polymorphic tool vs. several named tools?~~ **Resolved:** one `probe_data` tool taking the SPJQ query object, plus `describe_data` for schema. Degenerate shapes cover count / distinct / sample / aggregate, so there's nothing extra to select between. -2. ~~**Auto vs. explicit live fallback in `describe_data`:** fire `get_metadata` automatically whenever columns are missing vs. require `live=true`?~~ **Resolved:** always auto — `describe_data` fires `get_metadata` automatically whenever a table node's cached columns are missing (one query per described table), no `live` flag. The per-turn probe budget (§7) caps runaway calls. -3. ~~**Where does the local-compute default run?** Loader process vs. the agent's DuckDB sandbox.~~ **Resolved — reframed:** there is no universal local-compute *default*. DB systems don't local-compute at all (Strategy A pushes down); file sources read-and-compute **inside the loader** via DuckDB over the actual files (Strategy B), and the rare sample fallback (Strategy C) also runs loader-side. Compute never happens in the agent's `scratch/` sandbox — connector concerns stay in the loader. -4. ~~**Cache write-back conflicts:** how to merge probed columns with a later full `sync_catalog_metadata`?~~ **Resolved — dropped:** we stay agentic and do not write probe results back to the cache (§3.6 / §6.3), so there's no merge conflict to manage. -5. ~~**Cost controls for metered sources** (BigQuery/Athena bytes-scanned): should `probe` require a dry-run byte estimate and refuse above a threshold?~~ **Resolved — not for now.** No dry-run byte estimate in v1; the row/time/byte caps (§7) already bound each probe. Revisit if a metered source proves expensive in practice. -6. ~~**Do we ever want a genuine escape hatch** (a vetted, read-only, sandboxed raw-query capability), gated behind a flag?~~ **Resolved — no.** No raw-query escape hatch, not even flagged. It reintroduces the raw-query risk §3.1 forbids, multiplies the per-dialect sandbox + cost-control burden (each backend has different ways to smuggle side effects / blow up cost), and isn't needed: `probe` covers single-table reads and joins/expressions go through DuckDB `execute_python` (§10). A genuine gap the structured vocabulary can't express is closed by adding a *typed* operator to `probe` (e.g. the date-bucketing follow-up), never by opening a raw hole. - ---- - -## 10. Non-goals - -- Raw LLM-authored SQL/KQL to drivers (violates §3.1). **No escape hatch, not even flagged** (§9.6): the per-dialect read-only-sandbox + cost-control burden outweighs the benefit, and typed `probe` operators + DuckDB `execute_python` cover the real needs. -- Reworking the post-load Data Agent (analysis side) — this is the loading agent only. -- Write/ingest changes — `ingest_to_workspace` / `fetch_data_as_arrow` load path is unchanged; `probe` is a read-only sibling that shares the same query shape. -- **Joins / multi-table probes** — `probe` is single-table by design (the "J" is dropped on purpose). Cross-table work is done by loading both tables and joining in DuckDB via `execute_python`. -- **Computed expressions / raw fragments in `probe` v1** — only bare columns + the fixed aggregate ops. (Date-bucketing like `bin(ts, 1d)` / `date_trunc` is the most likely early follow-up, added as a structured field, never as raw text.) -- Persistent agent "cwd" state — calls stay stateless with explicit `(source_id, path)` (consistent with design 32).

You can have your agent generate simple chart specs -that users can edit — but they look bad (wrong sizing, misleading -encodings). Or you can have it generate polished specs — but they're -brittle (hard-coded values break on every field swap, and every edit -requires another LLM call). Either way, you're encoding design knowledge -in prompts — and **prompts are not a reliable way to encode design -knowledge.** Your agent may or may not follow them, and the result varies -across models, prompt versions, and even runs. Worse, if you need to -support multiple charting backends (Vega-Lite for composition, ECharts -for interactivity, Chart.js for lightweight embedding), **every prompt, -every example, every post-processing rule must be duplicated per -backend** — multiplying the brittleness. - -**Agents-chart** is a library that moves design knowledge out of your -prompts and into deterministic code. Instead of generating low-level -charting code, your agent outputs a minimal semantic description: chart -type, field assignments, and a **semantic type** per field (e.g., -`Revenue`, `Rank`, `CategoryCode`). Agents-chart's compiler -deterministically derives all low-level parameters — axis sizing, -zero-baseline behavior, formatting, color schemes, bespoke mark -templates — producing charts that look good *and* stay editable without -calling your agent again. The quality is consistent because it comes from -the library, not from the model. - -Because the semantic layer is **library-agnostic**, the same spec compiles -to multiple rendering backends — Vega-Lite, ECharts, Chart.js, and GoFish -today, with Plotly or D3 tomorrow — without re-deriving any design rules -and without duplicating any prompts. The expensive work (semantic -reasoning, layout computation) is done once; only the final instantiation -step differs per backend. - ---- - -## The Problem - -### What you deal with today - -You're building an agent that needs to create charts. Maybe it's a data -analysis copilot, a dashboard generator, or an automated reporting -pipeline. At some point your agent has to produce a visualization — and -that's where the brittleness starts. - -The typical approach: your agent generates Vega-Lite (or ECharts options, -or Plotly traces) directly. You write prompt templates with examples, -add post-processing logic for edge cases, build retry loops for malformed -output. It works for your demo. Then real users arrive with real data, -and the charts break in ways you didn't anticipate. - -Here is what goes wrong: - -1. **Inconsistency across runs.** Your agent produces variable output - quality — incorrect encodings, broken layouts, poor aesthetic defaults. - You tune prompts for one chart type and break another. Even with - detailed prompts specifying exact sizing rules, formatting conventions, - and encoding guidelines, **your agent may or may not follow them** — - and the degree of compliance varies across models, prompt versions, - context length, and even individual runs. Weaker models (the ones you - want to use for cost) struggle with anything beyond basic charts; even - frontier models fail on composition, faceting, and layered designs. - Design knowledge encoded in prompts is inherently unreliable. - -2. **The quality–editability trap.** If your agent generates simple code, - users can edit it (swap a field, change chart type) — but the chart - looks mediocre. If your agent generates polished code, the chart looks - great — but every user edit breaks it, forcing another round-trip to - your agent. You can't have both, and neither option makes users happy. - -3. **Expensive and slow for what it does.** Only frontier models - *sometimes* produce correct specs for non-trivial charts, because the - parameter space (axis types, domain settings, sizing, formatting, mark - config) is large and inter-dependent. Even then, compliance with your - design guidelines is probabilistic — you're paying frontier-model - prices for output that still needs validation and retry. Your agent is - spending its most expensive tokens on visualization plumbing instead of - the data computation that actually matters. - -4. **Ugly failure modes that you can't catch.** When your agent's output - breaks, the chart doesn't degrade gracefully — it produces extreme - dimensions (10,000 px wide from high-cardinality facets), crashes the - renderer, or silently misrepresents the data. The charting library - gives only low-level errors that neither you, your users, nor your - agent can act on. - -### The brittleness cascade - -Every fix you apply to your agent's visualization pipeline creates new -problems: - -| What you try | What breaks next | -|-------------|------------------| -| Add sizing logic to prompts | Hard-coded for this data shape; breaks on different cardinality | -| Add more VL examples to prompts | Token count balloons; model cost rises; unrelated examples confuse the model | -| Post-process the output (fix widths, rotate labels) | You're now maintaining VL manipulation code that couples to every chart type | -| Validate output and retry on failure | More LLM calls, more latency, more cost; retry loops don't fix *semantic* errors (wrong encoding type) | -| Constrain output with JSON schema | Schema can enforce structure but not *correctness* — `{"type": "quantitative"}` is valid JSON for a CategoryCode field but produces a meaningless chart | -| Support a second charting library (e.g., ECharts for interactivity) | All your prompt templates, post-processing, and validation must be duplicated for the new API | - -This is the **agent developer's treadmill**: you keep patching -visualization edge cases instead of building the data analysis features -that differentiate your product. - -### Why the obvious approaches don't work - -#### Approach 1: Have your agent generate minimal VL (rely on defaults) - -**Result: The spec is simple and editable, but the charts look bad — -and bespoke charts are impossible.** - -This is the "keep it simple" approach: your agent generates just field -names, mark type, and data. The spec is easy for users to edit — swap a -field name and the chart re-renders. But the *quality* of what renders is -poor, because VL's defaults are generic heuristics that ignore both data -characteristics and semantic meaning. - -**Sizing failures** — the chart is the wrong size for the data: - -| Scenario | VL default | What's wrong | -|----------|-----------|-------------| -| **Bar chart, 80 products** | `step: 20` → 1600 px wide | Overflows any container. Forces horizontal scrolling; unusable without a giant monitor. | -| **Grouped bar, 30 × 5** | 30 × 5 × 20 = 3000 px | Grouped bars multiply the problem: each product group has 5 sub-bars at 20 px each. | -| **Bars on temporal X (daily)** | VL doesn't auto-band temporal | Bars overlap or collapse to 1 px. Temporal axes are continuous; VL has no step-based sizing for them. | -| **Line chart, 15 series** | Fixed `height: 300` | 15 lines in 300 px → ~20 px per series. Unreadable spaghetti. | -| **Scatter, 2000 points** | Fixed 400 × 300 | Total mark area (156K px²) exceeds canvas area (120K px²). A solid blob. | -| **80 product labels** | No auto-rotation | Labels overlap into an unreadable smear. | - -**Composition makes it worse.** These problems compound — every -single-view sizing failure gets multiplied by the number of facets, and -`xOffset` (grouped bars) adds another multiplicative factor: - -| Scenario | VL default | What's wrong | -|----------|-----------|-------------| -| **80 products, 4 facets** | 4 × 1600 px subplots | 6400 px total — comparison between facets is impossible because they're screens apart. | -| **Grouped bar, 30 × 5, faceted × 4** | Facet × xOffset × step all multiply | 4 facets × 30 products × 5 groups × 20 px = 12,000 px. No way to express "fit everything within 800 px." | -| **Facet columns + subplot width** | Must hard-code both `columns` and `width` | Interdependent: 4 columns → each subplot 190 px (unreadable). 2 columns → wider but taller. VL has no coordination mechanism. | - -**Semantic failures** — the chart misrepresents the data: - -The same number can mean completely different things, and VL defaults -can't tell the difference. - -`17329487239` could be a **Unix timestamp**, a **Customer ID**, **Revenue -($)**, or a **sensor reading** — each requiring different encoding type, -zero behavior, formatting, and color scheme. VL sees a number and defaults -to `quantitative`. If it's a customer ID, you get a continuous axis from -0 to 17 billion with a single dot. If it's a timestamp, you get raw -numbers instead of dates. - -`1, 2, 3, 4, 5` could be **Rank**, **Star rating**, **Quantity**, -**Category code** (1=North, 2=South…), or a **Likert score** — each -needing different zero behavior, scale direction, tick formatting, and -chart compatibility. VL treats all as `quantitative, zero: true, -ascending`. For Rank, this means rank 1 (best) at the bottom, zero -wasted, ticks at "2.5" — absurd. - -You can't solve this in your agent's prompt or in post-processing. -Simple heuristics don't help: Rank, Rating, Quantity, Category code, -and Likert are all integers with identical cardinality. The only way to -know the correct encoding is to know what the data *means*. - -**Bespoke charts are out of reach.** This approach can't produce bump -charts, candlestick charts, streamgraphs, waterfall charts, or radar -plots. Minimal VL generation only covers basic bar / line / scatter / area. - -**Bottom line:** The simple approach keeps your agent cheap and fast, but -your users get wrong-sized, semantically misleading charts limited to -basic types. - -#### Approach 2: Have your agent generate polished VL - -**Result: The charts look great once, but every user edit breaks them — -and your agent gets called for every interaction.** - -This is the "invest tokens in quality" approach. Your agent generates -detailed VL with tuned sizing, formatting, and encoding. It achieves -quality precisely by **hard-coding values tuned to the current data**: - -| Hard-coded value | Breaks when… | -|------------------|-------------| -| `"width": 800` | User filters to 5 products (massive empty bars) or adds 200 (unreadable) | -| `"labelAngle": -45` | User swaps X to Region (3-letter labels don't need rotation) | -| `"domain": [0, 950000]` | User swaps Y to Temperature (wrong by 6 orders of magnitude) | -| `"mark.size": 8` | User switches to scatter with 1000 points (dots overlap completely) | -| `"scale.zero": true` | User swaps Y to Rank (zero-based rank wastes space, reads inverted) | -| `"format": "$,.0f"` | User swaps Y to Percentage (shows "$48" instead of "48%") | - -The better your agent's output, the *more* hard-coded constants it -contains, and the *harder* the chart is to edit. This creates a vicious -cycle: **high-quality generation → brittle spec → forced regeneration -on every edit → high cost and latency → poor exploration experience.** -As the agent developer, you're paying for this cycle in API costs, user -frustration, and engineering time spent on retry logic. - -**The parameters live at different levels and must coordinate.** A polished -VL spec scatters its configuration across multiple layers that all couple -to each other: - -| Level | Examples | Coordinates with | -|-------|---------|-----------------| -| **Global** | `width`, `height`, `autosize`, `padding` | Step size, facet columns, mark size | -| **Per-axis** | `scale.zero`, `scale.domain`, `scale.type`, `axis.format`, `axis.labelAngle` | Global width (label overflow), mark type (zero behavior), encoding type | -| **Per-mark** | `mark.size`, `mark.strokeWidth`, `mark.opacity` | Global dimensions (overlap), data cardinality | -| **Composition** | `facet.columns`, `resolve.scale`, `xOffset.step` | Global width (subplot size), per-axis step (bar width), label config | - -Editing any one parameter without adjusting the others produces a -broken chart. Change `width` from 800 to 400? The label angle, step -size, and font size were tuned for 800 — now labels overlap. Add a -facet column? The per-subplot width halves, so bars become unreadable -unless you also shrink the step, rotate labels, and adjust font size. -Switch from bar to scatter? `scale.zero`, `mark.size`, and `domain` -all need updating, but `width` and `labelAngle` might also change -because scatter points have different spatial needs than bars. - -This coordination is **the core brittleness problem for agent developers.** -You can't encode it in a prompt. A rule-based post-processor would need -to enumerate the full cross-product of parameter interactions. Neither is -practical — which is why every edit becomes another LLM call from your -agent. - -**Structural rewrites are the worst case.** Swapping Product→Year and -Revenue→Rank transforms a bar chart into a bump chart: the mark changes -from bar to line+circle (layered), X type changes from nominal to ordinal, -Y gets reversed with `zero: false` and domain padding, a color channel -appears, and width/height both change. No single-parameter edit path -exists — it's a complete structural rewrite. - -**The alternative: call your agent for every edit.** This works, but: - -- **Expensive for you.** ~500–1000 tokens per call × 10–15 edits in a - session = significant API cost. Each call takes 2–5 seconds. -- **Forces you to use expensive models.** Only frontier models reliably - handle bespoke charts with their layered marks, data transforms, and - complex scale configurations. -- **The $F \times C$ combinatorial problem.** With 15 fields and 5 chart - types, there are 75 possible configurations. Your agent handles each one - individually — dozens of calls per exploration session. - -**Bottom line:** Polished VL generation looks good once, but the spec is -too complex to edit, and regeneration per edit is slow, expensive, and -requires frontier models. - ---- - -## The Solution - -The core insight: **design knowledge belongs in the library, not in your -prompts.** Your agent may or may not follow a detailed prompt — and even -when it does, the result varies across models and runs. Agents-chart -eliminates this uncertainty by encoding all visualization design decisions -in deterministic code. Your agent generates a minimal spec, and the -library handles everything else — consistently, every time, regardless of -which model produced the spec. - -### What your agent does differently - -- **A simple output contract.** Your agent outputs a small JSON: chart - type, field assignments, and a semantic type per field. No axis config, - no sizing, no formatting, no mark layering. This is easy for any model - to produce reliably — even cheap, fast models. The contract is small - enough that compliance is near-certain, unlike detailed prompts with - dozens of design rules that models follow inconsistently. - -- **Automatic, consistent quality.** The library compiles that JSON into - a polished chart with correct sizing, formatting, zero-baseline - behavior, color schemes, and label handling — every time, deterministically. - The design knowledge is built into the compiler, not hoped for from the - model. Your agent doesn't need to know Vega-Lite (or ECharts, or - Chart.js) at all. - -- **User edits without calling your agent.** Users can swap fields, change - chart types, add facets — and the chart re-derives all low-level config - automatically. **90% of edits need zero LLM calls.** Your agent is only - invoked for the initial chart creation and for data transformations. - -- **Bespoke charts at no extra prompt cost.** Grouped bars, bump charts, - streamgraphs, candlesticks, ridge plots — they all take the same ~7-line - spec as a basic bar chart. The templates in the library handle the mark - layering, custom transforms, and specialized encodings. - -- **Actionable error messages.** When a chart configuration is wrong, the - library produces semantic explanations (*"Pyramid chart requires exactly - 2 categories; 'Region' has 5"*) that your agent can read and repair — - no VL stack traces, no silent misrepresentation. - -- **Multi-backend output from one spec.** The same semantic spec compiles - to Vega-Lite, ECharts, Chart.js, or GoFish. Your deployment context - picks the backend; your agent and your prompts don't change. - -- **The generated output is still accessible.** Agents-chart compiles to - standard Vega-Lite (or ECharts options, or Chart.js configs). If a user - needs to fine-tune a specific visual detail, they can edit the generated - output directly. The library handles the 98% of decisions derivable from - semantics; users override the remaining 2%. - -### At a glance - -| Property | Approach 1 (defaults) | Approach 2 (polished VL) | Agents-chart | -|----------|-----------------------|--------------------------|--------------| -| **Looks good** | ✗ | ✓ | ✓ | -| **Editable** | ✓ (simple spec) | ✗ (brittle, hard-coded) | ✓ (semantic spec) | -| **Bespoke charts** | ✗ | Sometimes (frontier model) | ✓ (templates) | -| **Cost per user edit** | 0 (no agent call) | 1 agent call ($, latency) | 0 (no agent call) | -| **Agent complexity** | Low (just fields + mark) | High (coordinate 10–30 params) | Low (fields + semantic types) | -| **Model requirement** | N/A | Frontier for bespoke | Any (classification only) | - -### How your agent integrates - -``` -1.

The user/LLM never touches layered marks, - custom transforms, or scale configurations. - -4. **No UI dependencies.** Zero React, Redux, or framework imports. - Pure TypeScript library usable from any context. - -### Two-Stage Pipeline - -Each backend has its own `assemble*()` entry point (`assembleVegaLite`, -`assembleECharts`, `assembleChartjs`, `assembleGoFish`), but they all -follow the same two-stage structure. The analysis stage is shared; -only the instantiation stage is backend-specific. - -``` -assembleVegaLite(input: ChartAssemblyInput) // or assembleECharts, assembleChartjs, assembleGoFish - │ - ▼ - ══ ANALYSIS (backend-free, shared core) ═════════════════════ - │ - ├── Phase 0: resolveSemantics() → ChannelSemantics - │ Infers encoding type, zero-baseline, color scheme, - │ format, aggregation default, scale type, domain, - │ temporal format for each channel from semantic types - │ + data characteristics. - │ - ├── Step 0a: template.declareLayoutMode() → LayoutDeclaration - │ Template hook: declares axis flags (banded?), - │ type overrides, param overrides, overflow strategy. - │ - ├── Step 0b: convertTemporalData() → converted data - │ Parses temporal string values into Date objects. - │ - ├── Step 0c: filterOverflow() → OverflowResult - │ Truncates discrete channels that exceed the canvas - │ budget.

Semantic types as the contract - -The root cause of your agent's brittleness is that charting APIs scatter -the semantic contract between data and chart across dozens of low-level -parameters. Consider a column containing `17234982372` — it could be a -Unix timestamp, a monetary value, a serial number, or a group ID. Today, -your agent must decide the encoding type (`temporal`, `quantitative`, -`nominal`), set axis formatting, configure zero-baseline behavior, choose -sizing — and these become hard-coded constants in the output that break -when the user edits anything. - -**The fix:** instead of asking your agent to set these low-level details, -ask it to communicate one thing: **what does this data mean?** — expressed -through a fine-grained semantic type system (e.g., `Revenue`, `Rank`, -`Temperature`, `Year`). From the semantic type plus data characteristics -(cardinality, range, distribution), agents-chart's compiler automatically -derives everything: - -``` -Semantic type - ↓ - ├── Encoding type (Revenue → quantitative, Rank → ordinal, Month → ordinal) - ├── Zero baseline (Revenue → true, Temperature → false, Rank → false) - ├── Domain padding (Rank → 8%, Temperature → 5%, Revenue → 0%) - ├── Scale direction (Rank → reversed, others → normal) - ├── Axis formatting (Revenue → "$,.0f", Percentage → ".0%", Year → "%Y") - ├── Sort order (Month → calendar order, Product → by value) - ├── Color scheme (Company → categorical, Revenue → sequential) - └── Sizing model (nominal → spring, quantitative → per-axis stretch) -``` - -Your agent's only job is **semantic classification** — assigning a type -like `"Revenue"`, `"Rank"`, `"Temperature"`, or `"Month"` to each data -field. This is one of the easiest tasks for any LLM (even small, fast -models do it reliably). - -**Semantic types survive user edits.** When the user swaps Y from -Revenue to Temperature, agents-chart re-derives all parameters from -`"Temperature"` instead of `"Revenue"` and gets the right answer. No -hard-coded constant goes stale because there are no hard-coded constants. -**Your agent is not called.** - -**The $F \times C$ problem becomes $F + C$.** Your agent classifies each -field once ($F$ decisions), the user picks a chart type ($C$ choices), -and agents-chart handles the cross-product. Instead of 75 configurations -that each need an agent call, the system needs 15 type assignments (done -once) and handles all 75 deterministically. - -→ Full semantic type system details: -[design-semantics.md](design-semantics.md) - -### 2. Parametric physics instead of manual heuristics - -The layout challenge is **coordinating sizing across axes, layers, mark -types, and facets** — parameters that are deeply interdependent (e.g., -facet count affects subplot width, which affects bar width, which affects -label rotation). - -The conventional approach — whether done by your agent, by hand-coded -post-processing, or by the charting library's defaults — is -**heuristic-based**: a pile of if/else rules and magic numbers -(`if bars > 30, rotate labels; if width > 800, shrink step`). These -heuristics are brittle because they don't compose: every new chart type, -every new facet structure, every new mark combination requires new rules. -You're always guessing thresholds, and the guesses break on data shapes -you didn't anticipate. - -Agents-chart replaces this with a **parametric physics-inspired model**. -Instead of guessing layout constants, you control the system through a -small set of physics parameters with intuitive physical meaning: - -| Parameter | Physical meaning | What it controls | -|-----------|-----------------|------------------| -| $\ell_0$ (rest length) | Natural spacing between items when unconstrained | Default bar/cell width before any compression | -| $k$ (spring stiffness) | Resistance to compression | How aggressively items shrink to fit the canvas | -| $\ell_{\min}$ (min length) | Hard floor — items never compress below this | Minimum readable bar/cell width | -| $W_{\max}$ (max canvas) | Maximum allowed canvas width | Upper bound on chart dimensions | -| $\beta_f$ (facet stretch) | How much extra canvas a facet adds | Trade-off between subplot density and total chart width | -| $P$ (pressure) | Outward force from continuous data density | How much a dense scatter/line plot stretches its canvas | - -These parameters **compose naturally**. A faceted grouped bar chart doesn't -need special-case rules — the spring model runs per subplot, facet stretch -adjusts the container, and the parameters interact through the same physics -equations regardless of chart type. Change one parameter (e.g., raise -$\ell_{\min}$ to guarantee wider bars) and the system re-equilibrates -automatically — no cascade of broken heuristics. - -**Spring Model (Discrete Axes).** Applies to banded marks (bar, histogram, -heatmap, boxplot, grouped bar). Models the axis as $N$ springs in a box: - -$$\ell = \frac{\kappa \cdot \ell_0 + L_0 / N}{1 + \kappa}$$ - -Three regimes: **Fits** (items at natural size), **Elastic** (items -compress + axis stretches), **Overflow** (items at minimum, excess -truncated). - -**Gas-Pressure Model (Continuous Axes).** Applies to positional marks -(scatter, line, area, bump). Each axis stretches based on 1D crowding -pressure: - -$$s = \min\!\big(1 + \beta_c,\; p^{\,\alpha_c}\big)$$ - -Two pressure modes: **positional** (unique pixel positions × √σ / dim) -and **series-count** (nSeries × σ / dim for line/area Y axes). - -**Facet Model.** Second-level stretch for faceted charts. Each subplot -runs its own sizing model internally; the facet layer determines subplot -count, columns, and overall canvas growth. - -→ Full layout model details: -[design-stretch-model.md](design-stretch-model.md) - -### 3. Library-agnostic multi-backend architecture - -Both semantic types and physics-based sizing are **library-agnostic** — -they reason about data meaning and visual density, not about any -particular charting API. This means the same compiler logic targets -multiple rendering backends without re-deriving the design rules. - -As an agent developer, you may need to deploy to different contexts — -a lightweight mobile app, a desktop analytics tool, a static report. -No single charting library fits all of them: - -| Backend | Strengths | Weaknesses | -|---------|-----------|------------| -| **Vega-Lite** | Grammar of graphics; declarative composition; strong faceting and layering | Heavy runtime (~400 KB); limited interactivity beyond tooltips; poor mobile performance | -| **ECharts** | Rich interactivity (zoom, brush, dataZoom); Canvas + SVG dual renderer; strong CJK locale support | Imperative option-bag API; no grammar-of-graphics composition; verbose config for layered designs | -| **Chart.js** | Lightweight (~60 KB); Canvas-native (fast for large datasets); simple API; massive plugin ecosystem | No faceting; limited statistical charts; no declarative composition | -| **GoFish** | Imperative rendering; full control over mark placement | No built-in layout or scale system | - -**These are not interchangeable APIs with different syntax — they use -fundamentally different visual representation models and data models.** -Adapting between them is highly non-trivial: - -- **Vega-Lite** is a *grammar of graphics*: a chart is a composition of - independent encoding channels (x, y, color, size, shape) bound to data - fields through scales. Layering and faceting are declarative - compositional operators. Data flows through a transform pipeline into - a single flat table. - -- **ECharts** is an *option bag*: a chart is a top-level config object - with `series[]` arrays, each containing its own data, mark type, and - axis bindings. There are no encoding channels — you configure axis - objects directly and reference them by index. Layering means adding - series entries; faceting has no native concept. - -- **Chart.js** is a *dataset-oriented canvas renderer*: a chart has a - single chart type, a `labels` array for the categorical axis, and - `datasets[]` with parallel value arrays. There is no independent - encoding model — color, border, and point style are per-dataset - properties, not data-driven channels. Composition beyond basic - stacking doesn't exist. - -These differences mean you can't transliterate a spec from one library -to another — you must *re-think* the chart in each library's conceptual -model. Without a backend-agnostic library, supporting multiple renderers -means **duplicating your entire agent pipeline per backend** — prompts, -examples, post-processing, validation, retry logic, sizing heuristics. -This is the $B \times T \times R$ explosion: $B$ backends × $T$ -templates × $R$ rules. - -**Agents-chart collapses this to $T + (B \times I)$.** The $T$ templates -and $R$ rules live in shared Phases 0–1, and each backend only implements -$I$ instantiation functions — thin translators that map the -already-computed layout into the target library's config format. Adding a -new backend means writing instantiation code, not re-implementing the -design system. - -**What this means for you:** - -- **Deployment flexibility.** A mobile app uses Chart.js (60 KB); a - desktop analytics tool uses Vega-Lite (full composition). Your agent - generates one spec; the deployment target picks the backend. - -- **Capability coverage.** Radar and gauge charts are native in ECharts - but missing from Vega-Lite. Faceted compositions are native in Vega-Lite - but painful in Chart.js. Agents-chart routes each chart type to the - backend that handles it best — your agent doesn't need to know which. - -- **Rendering trade-offs handled for you.** Canvas renderers handle 10K+ - points without DOM pressure; SVG renderers produce crisper output for - publication. The choice depends on dataset size — not on your prompts. - -- **Vendor independence.** When agents-chart is the contract — not the - backend API — swapping or upgrading a renderer is a localized change, - not a rewrite of your entire pipeline. - -- **New backends are easy to add — even by coding agents.** Adding a - backend is a *mechanical translation* task: given the computed layout - and a target library's API, write the instantiation functions. This - is exactly what coding agents (Copilot, Cursor, Codex) excel at — they - can scaffold a new backend from existing ones as reference. Developers - and designers then enhance the generated adapters with domain-specific - design knowledge: animation defaults, theme integration, accessibility, - or library-specific optimizations. The result is a - **human-in-the-loop backend pipeline** where the mechanical work is - automated and design expertise is applied where it matters most. - -### 4. Error handling - -When your agent generates raw VL and the chart fails, failures are either -**catastrophic** (the chart crashes or renders at 2000 px × 80 px) or -**silent** (the chart misrepresents the data). VL gives only low-level -errors that neither your agent nor your user can act on. - -With agents-chart, your agent gets **structured, semantic error messages** -that it can parse and repair automatically. - -**Semantic validation — agents-chart catches errors before rendering:** - -| Violation | What agents-chart detects | What raw VL does | -|-----------|--------------------------|-----------------| -| **Chart–data incompatibility** | *"Pyramid chart requires exactly 2 categories; 'Region' has 5"* | Renders a broken layered bar chart. No error. | -| **Redundant encoding** | *"Revenue is mapped to both Y and color — color adds no information"* | Renders silently with a meaningless gradient legend. | -| **Field–channel mismatch** | *"Product has 80 values — too many for a color encoding"* or *"Group is a CategoryCode — use nominal, not quantitative"* | Renders 80 indistinguishable colors, or maps numeric categories to a continuous gradient. No warning. | -| **Missing required encoding** | *"Candlestick chart requires Open, High, Low, Close fields"* | Crashes or renders partial marks. No explanation. | - -**Overflow detection — agents-chart explains *why* a chart was clipped:** - -| Scenario | Agents-chart response | Raw VL result | -|----------|----------------------|---------------| -| **80 products × 4 facets** | *"X axis clipped: 80 products compressed from 20 px to 8 px per bar; canvas stretched to 800 px (max). Consider filtering to top 20."* | 6400 px wide, or 400 px with 5 px bars. No explanation. | -| **720 temporal cells** | *"Heatmap X axis: 720 hourly cells compressed to 1.1 px each. Consider aggregating to daily."* | 14,400 px wide, or 0.5 px cells — a solid color band. | -| **50 facets × 10 categories** | *"Facet overflow: 50 subplots cannot fit readable bars. Showing top 12 facets; 38 truncated."* | 50 squished facets with 0.8 px bars. Technically renders but useless. | - ---- - -## Abstract Channels - -The library defines its own channel vocabulary, distinct from VL encoding -channels. This decouples user/AI intent from rendering specifics. - -| Channel | Purpose | VL translation | -|---------|---------|----------------| -| `x`, `y` | Positional axes | Direct mapping | -| `x2`, `y2` | Range endpoints (ranged dot, waterfall) | Direct mapping | -| `color` | Color encoding | Direct mapping | -| `group` | Grouped subdivision (e.g., grouped bar) | VL `color` + `xOffset`/`yOffset` | -| `size` | Mark size (scatter) or slice weight (pie) | Scatter: VL `size` with sqrt scale; Pie: VL `theta` | -| `shape` | Mark shape | Direct mapping | -| `opacity` | Opacity | Direct mapping | -| `column`, `row` | Faceting | VL `facet`/`column`/`row` | -| `detail` | Detail level without visual change | Direct mapping | -| `latitude`, `longitude` | Geo coordinates | Direct mapping | -| `open`, `high`, `low`, `close` | Candlestick price channels | Layered rule + rect encoding | -| `radius` | Radar chart radius | VL `radius` with sqrt scale | - -### The `group` channel - -First-class channel for grouped bar charts. The analysis stage resolves -its semantics (type, color scheme) without any VL knowledge.

VL's defaults happen to work: 5 bars fit -comfortably, `zero: true` is correct, alphabetical sort is acceptable. -**No win here — and that's the point.** Agents-chart isn't designed to help -with cases your agent already handles well. - -### Example 2: Lollipop chart — templates eliminate prompt complexity - -**Task:** Lollipop chart of Revenue by Product (top 10), colored by Group -(values: 1, 2, 3, 4, 5 — categorical groups encoded as numbers). - -**With agents-chart:** Chart type = "Lollipop Chart", three field encodings -(x, y, color), three semantic types (`Revenue`, `Product`, -`CategoryCode`). Same ~10 lines as any chart. - -**What your agent's prompt must produce if generating VL directly:** - -| VL parameter | What and why | -|-------------|-------------| -| Layered spec structure | Must use `layer: [...]` — a lollipop is two marks, not one | -| Rule mark config | `mark.type: "rule"`, `strokeWidth`, `color` for the stem | -| Circle mark config | `mark.type: "circle"`, `size`, `color` for the dot | -| Duplicated encoding | Both layers need identical `x`, `y`, and `color` encodings | -| Sort | `sort: "-x"` on the Y axis to rank products by value | -| Zero baseline | `scale.zero: true` on the X axis (Revenue is zero-meaningful) | -| Step size | VL default step (20 px) works here for 10 items, but breaks if data grows | -| Axis formatting | `axis.format: "~s"` for compact numbers | -| Color encoding type | Group values are `1, 2, 3, 4, 5` — VL defaults to `quantitative`, producing a continuous blue gradient. Must set `"type": "nominal"` for categorical colors. | -| Color scale scheme | Must override to categorical palette (`"category10"`) — but only after fixing the type. | - -The color problem is especially insidious: VL sees numbers and defaults to -`quantitative` with a sequential color scheme. Groups 1 and 2 get nearly -identical shades of blue — visually indistinguishable. The chart *renders* -without error but the color encoding is meaningless. With agents-chart, -`CategoryCode` → nominal → categorical palette, and groups get distinct -hues automatically. - -### Example 3: Faceted bar chart — physics layout vs. hard-coded sizing - -**Task:** Revenue by Product (80 products), faceted by Region (4 regions). - -**With agents-chart:** Chart type, three field encodings (x, y, column), -three semantic types. Same ~12 lines. - -**What your agent must hard-code if generating VL directly:** - -| Problem | What VL requires | Why it's hard | -|---------|-----------------|---------------| -| **Canvas size** | Hard-code `width` per subplot + `columns` for facet wrap | VL default: 20 px × 80 = 1600 px per subplot → 4 facets = 6400 px total. Must override, but numbers depend on each other. | -| **Step / bar width** | Hard-code `step` or `width` | With `width: 380` for 80 bars, each bar is ~4.75 px — unreadable. Must add `labelAngle: -90`, `labelLimit: 60`, `labelFontSize: 9`. | -| **Facet wrapping** | Hard-code `columns` | 4 columns → each subplot 190 px (unreadable). 1 column → page 4× taller. The right choice depends on bar count, label length, container size. | -| **Scale resolution** | `resolve.scale.x: "independent"` | Each facet may have different products — shared scale wastes space. | - -Your agent's prompt can't express these dependencies — each value must be -hard-coded, and they all break when the data changes. - -With agents-chart, the spring model handles all four automatically: -- Facet stretch ($\beta_f$) determines overall canvas growth. -- Each subplot's spring model: 80 products × $\ell_0 = 20$ px overflows → - items compress to $\ell = 8$ px, subplot stretches to fit. -- Label rotation and truncation derived from count and string lengths. -- Result: readable bars (8 px, not 2 px), controlled total width (not - 6400 px), facet columns balanced. Your agent doesn't touch any of this. - -### Example 4: Heatmap with temporal × category — semantic types vs. guessing - -**Task:** Heatmap of event counts — UTC timestamps (hourly, 30 days) on X, -Category (15 event types) on Y, count as color. - -**With agents-chart:** Chart type = "Heatmap", three encodings (x, y, -color), three semantic types (`DateTime`, `Category`, `Count`). ~12 lines. - -**What your agent must get right if generating VL directly** — 11 -decisions, all stemming from needing to know what the data *means*: - -| Decision | What VL requires | What agents-chart derives | -|----------|-----------------|--------------------------| -| X encoding type | `"type": "temporal"` — must recognize timestamp is a date, not a number | `DateTime` → temporal | -| Time formatting | `"format": "%m/%d %H:%M"` — must pick format for hourly granularity | `DateTime` + hourly range → appropriate format | -| UTC scale | `"scale": { "type": "utc" }` — must know timestamps are UTC | `DateTime` → UTC handling | -| Time unit | `"timeUnit": "yearmonthdatehoursminutes"` — verbose, error-prone | Derived from data range + granularity | -| Label rotation | `"labelAngle": -45` — must guess from label width | Auto from label count + string length | -| Y encoding type | `"type": "nominal"` — must decide Category isn't quantitative | `Category` → nominal | -| Color zero baseline | `"scale.zero": true` — Count should start from 0 | `Count` → zero-meaningful → `zero: true` | -| Color scheme | `"scheme": "blues"` — sequential scheme for counts | `Count` → quantitative sequential → blues | -| Color format | `"format": "d"` — integer formatting for counts | `Count` → integer → `"d"` | -| Cell step size | VL default: 720 × 20 = 14,400 px wide. Must hard-code width. | Spring model: 720 cells → equilibrium at ~800 px | -| Canvas width | Hard-code `"width": 800` after manually computing 720 cells | Derived automatically from cell count + compression | - -That's **11 decisions your agent must make correctly**, all derived -automatically from three semantic type annotations. - -If the timestamp column contained Unix epoch numbers (e.g., `1739600400`), -VL would default to `quantitative` — a continuous axis from 0 to 1.7 -billion.

Each T2 type maps to exactly one T1 category. These provide the finest-grained compilation context. - -The T2 inventory is deliberately **pruned to types that change compilation behavior** vs. their T1 parent. Types that compile identically to a sibling are dropped — the LLM can use the T1 name instead.

The user is building a revenue chart, so the system asks for T2 annotation on the 3-4 likely chart fields (revenue, month, category) and T1 for the remaining 16 columns: - -```json -{ - "revenue": { "semantic_type": "Revenue", "unit": "USD" }, - "month": { "semantic_type": "Month" }, - "product_category": { "semantic_type": "Coded" }, - "customer_name": { "semantic_type": "Entity" }, - "customer_age": { "semantic_type": "GenericMeasure" }, - "region": { "semantic_type": "GeoPlace" }, - "order_date": { "semantic_type": "DateTime" }, - "satisfaction": { "semantic_type": "Score", "domain": [1, 5] } -} -``` - -Here `revenue`, `month`, and `satisfaction` get T2 types (fine-grained decisions). `product_category` and `customer_name` get T1 (enough for encoding and format class). When the user later drags `customer_age` onto a chart, the system can re-annotate that one field at T2 level. - -### 0.7 Multi-membership dimensions: orthogonal axes that drive visualization - -The tier hierarchy (T0→T1→T2) is ONE axis of the type system — it controls *which* compilation rules fire and at what granularity. But every semantic type also sits at a specific position along several **orthogonal classification dimensions**, each of which directly controls a distinct set of visualization properties. The compilation context is the *product* of tier-derived decisions **and** dimension-derived decisions. - -#### 0.7.1 The five orthogonal dimensions - -| Dimension | Values | What viz properties it controls | -|---|---|---| -| **Vis encoding candidates** | `quantitative`, `ordinal`, `nominal`, `temporal` (one or more, with preference order) | Axis type, scale type, mark compatibility, channel compatibility, sort | -| **Aggregation role** | `additive`, `intensive`, `signed-additive`, `dimension`, `identifier` | Whether to aggregate, which aggregate function, whether to group-by, tooltip-only | -| **Domain shape** | `open`, `bounded`, `fixed`, `cyclic` | Scale domain clamping, tick generation, extrapolation, axis extent, radar/polar recommendation | -| **Diverging nature** | `none`, `conditional`, `inherent` | Color scheme class (sequential vs diverging), midpoint, legend center, bipolar axis | -| **Format class** | `currency`, `percent`, `unit-suffix`, `date`, `time`, `integer`, `plain` | Axis label format, tooltip format, prefix/suffix, decimal precision | - -These dimensions are NOT derivable from the tier hierarchy alone — they are properties of each type that must be explicitly catalogued. Two types in the same T1 category can differ on multiple dimensions (e.g., `Temperature` and `Weight` are both `Physical` but differ on diverging nature). - -#### 0.7.2 Dimension → Visualization property mapping - -Each dimension controls a specific, non-overlapping set of downstream visualization decisions: - -**Vis encoding candidates** → determines: -- Whether a field can go on X/Y axis (quantitative/temporal/ordinal) vs only color/shape/facet (nominal) -- Scale type: `linear`, `log`, `time`, `point`, `band` -- Compatible mark types: quantitative fields → line/area/bar; nominal → bar/point; temporal → line/area -- Sort behavior: temporal → chronological; ordinal → canonical order; nominal → data order or alphabetical -- When a type has multiple valid encodings (e.g., `Rating` → Q or O), the builder picks based on chart type + channel: scatter Y → quantitative; heatmap color → ordinal - -**Aggregation role** → determines: -- Whether the field appears in the `aggregate` vs `groupby` clause -- Default aggregate function: `additive` → `"sum"`, `intensive` → `"mean"`, `signed-additive` → `"sum"` -- Whether the field should be offered as a measure or dimension in the UI -- `identifier` → excluded from aggregation entirely, tooltip-only - -**Domain shape** → determines: -- Scale domain: `open` → auto from data; `bounded` → clamp to known range; `fixed` → hard limits; `cyclic` → modular -- Tick generation: `bounded [0,100]` → nice ticks within range; `fixed [-90,90]` → constrained; `cyclic` → all cycle values -- Extrapolation: `cyclic` → no extrapolation beyond period; `open` → allow forecast extension -- Chart type hints: `cyclic` → radar/polar natural; `bounded` → gauge natural -- Axis padding: `bounded` → don't pad beyond bounds; `open` → allow padding -- Color interpolation: `cyclic` → wrap-around palette; `bounded` → clamp at edges - -**Diverging nature** → determines: -- Color scheme: `none` → sequential; `conditional` → sequential by default, diverging if data spans both sides; `inherent` → always diverging -- Midpoint: `inherent` → fixed center (0 for Profit, 0 for Sentiment); `conditional` → 0 if data crosses zero; `none` → N/A -- Domain-specific midpoints (e.g., pH=7, NPS=0, custom satisfaction scales) are derived from `annotation.intrinsicDomain` midpoint rather than type-intrinsic logic -- Legend symmetry: diverging → symmetric around midpoint; sequential → start at min -- Reference line: diverging → draw reference at midpoint; sequential → no reference - -**Format class** → determines: -- Axis label format string: `currency` → `$,.2f`; `percent` → `.1%`; `unit-suffix` → `,.1f kg` -- Tooltip format: same prefix/suffix, possibly more precision -- Number precision: `currency` → 2 decimal; `percent` → 1 decimal; `integer` → 0 decimal -- Prefix/suffix: `currency` → prefix ($, €, £); `unit-suffix` → suffix (kg, km, °C); `percent` → suffix (%) - -#### 0.7.3 Complete multi-membership table - -Every type occupies a position in the tier hierarchy AND a position along each orthogonal dimension.

The orthogonal dimensions provide **cross-cutting properties** that apply regardless of tier. Both are stored in the type registry: - -```typescript -// Each type in the registry carries its tier position AND its dimension values. -// Actual interface from core/type-registry.ts: -interface TypeRegistryEntry { - // Tier position - t0: T0Family; // 'Temporal' | 'Measure' | 'Discrete' | 'Geographic' | 'Categorical' | 'Identifier' - t1: T1Category; // e.g., 'Amount', 'DateGranule', 'Entity', etc. - - // Orthogonal dimensions (these drive viz properties directly) - visEncodings: VisCategory[]; // preference-ordered, e.g., ['quantitative', 'ordinal'] - aggRole: AggRole; // 'additive' | 'intensive' | 'signed-additive' | 'dimension' | 'identifier' - domainShape: DomainShape; // 'open' | 'bounded' | 'fixed' | 'cyclic' - diverging: DivergingClass; // 'none' | 'conditional' | 'inherent' - formatClass: FormatClass; // 'currency' | 'percent' | 'signed-percent' | 'unit-suffix' | 'date' | 'time' | 'integer' | 'plain' - zeroBaseline: ZeroBaseline; // 'meaningful' | 'arbitrary' | 'contextual' | 'none' - zeroPad: number; // domain padding fraction (e.g., 0.08 for Rank, 0.05 for Temperature) -} -``` - -> **Note on aggRole naming:** The design doc originally proposed `measure-sum` / `measure-avg` terminology. -> The implementation uses `additive` (summed: Revenue, Count), `intensive` (averaged: Temperature, Price), -> and `signed-additive` (summed but can go negative: Profit). The mapping is: -> `measure-sum` → `additive`, `measure-avg` → `intensive`, signed measures → `signed-additive`. - -When a type is recognized at T1 level, the builder inherits the T1 entry's dimension values. When recognized at T2, the T2 entry's values override. When only T0 is known, the builder uses conservative defaults for each dimension (e.g., `visEncodings: ['quantitative']` for Measure, `domainShape: 'open'`, `diverging: 'none'`). - -#### 0.7.5 Key design consequences - -1. **Vis encoding is not 1:1 with semantic type.** `Month` can be ordinal (bar chart categories) or temporal (time-series X). `Rating` can be quantitative (scatter Y) or ordinal (heatmap). The `visEncodings` array provides a *preference order* that the builder resolves based on chart type and channel. This is a first-class property of the type, not an afterthought. - -2. **Domain shape directly determines scale and tick behavior.** Both `Percentage` (T1: Proportion) and `Latitude` (T1: GeoCoordinate) have bounded domains but are in completely different T0 families. The builder queries `domainShape` independently of the tier — same logic applies to both. - -3. **Diverging nature directly determines color scheme.** This is not just a T2-level detail — it's an orthogonal dimension that T1 types can carry too. `SignedMeasure` (T1) carries diverging information; `Physical` (T1) is conditionally diverging (only `Temperature` within it, at T2 level). Domain-specific diverging midpoints (e.g., pH=7) are derived from `intrinsicDomain` midpoint rather than dedicated types. - -4. **Aggregation role determines aggregate function — and auto-aggregation.** `Revenue` and `Price` are both `Amount` (T1), but Revenue is `additive` while Price is `intensive`. This distinction lives in the orthogonal dimension, not in the tier hierarchy. Critically, the aggregation role is essential for **auto-aggregation in under-specified charts**: when a user creates a bar chart with X=`Month` and Y=`Revenue` but provides no color encoding, the dataset likely has multiple rows per month (e.g., per-product or per-region rows). Without explicit color to distinguish them, the system must auto-aggregate Y. Knowing Revenue is `additive` lets the instantiator emit `{"aggregate": "sum", "field": "Revenue"}` automatically. The same applies to line charts — multiple Y values per X point produce a jagged, unreadable line unless aggregated. The correct aggregate function (sum vs mean vs count) depends entirely on the field's aggregation role: Revenue→sum, Temperature→mean, row-count→count. Getting this wrong (e.g., summing temperatures) produces nonsensical charts. Auto-aggregation should be a **compiler option** — an explicit flag the caller passes to the instantiation phase, since some contexts (e.g., raw data preview, user explicitly wanting per-row marks) should suppress it: - - ```typescript - interface CompilerOptions { - autoAggregate: boolean; // when true, instantiator injects aggregate transforms - // for measure fields when multiple rows map to the same - // positional encoding (e.g., same X in a bar/line chart) - // ... other compiler options ... - } - ``` - -5. **The `FieldSemantics` is the resolved product of both axes.** Downstream code never reasons about tiers or dimensions directly — it gets a fully resolved context where encoding, format, aggregation, domain, diverging, etc. are all concrete values. - -#### 0.7.6 Intrinsic vs. data-dependent dimension values - -The dimension values in the type registry (§0.7.3, §0.7.4) are **intrinsic** — they reflect the type's nature independent of any specific dataset or chart. But some dimension values are only fully determined when combined with **actual data characteristics**: cardinality, distribution, range, null rate, etc. - -**Examples of data-dependent shifts:** - -| Intrinsic (from type) | Data signal | Effective (after data) | Reason | -|---|---|---|---| -| `Coded` → vis: nominal | Cardinality > 20 | Treat as quantitative or use top-N + "Other" | Too many categories → cluttered legend/axis | -| `Rating` → vis: [quant, ordinal] | Only 5 distinct values | Prefer ordinal | Small discrete set → ordinal ticks natural | -| `Rating` → vis: [quant, ordinal] | 100-point scale, continuous-looking | Prefer quantitative | Large range → continuous axis cleaner | -| `Country` → vis: nominal | 150+ countries | Consider top-N filtering or map instead of bar | Nominal with extreme cardinality → unreadable | -| `Year` → vis: [temporal, ordinal] | Only 3 values: 2022, 2023, 2024 | Prefer ordinal | Sparse temporal → ordinal ticks better | -| `Percentage` → domain: bounded [0,100] | Actual data range [45, 55] | Narrow domain, zoom in | Bounded but data clustered → auto-zoom | -| `GenericMeasure` → agg: heuristic | Field name contains "count" | additive | Name-based heuristic refines generic role | - -**Design decision: where does this happen?** - -This data-dependent resolution happens at **two distinct stages**, not one: - -1. **Context determination time** (`resolveFieldSemantics`): The builder can use data statistics (cardinality, min/max, distinct count) to **disambiguate** the intrinsic dimension values. For example, `Rating` has `visEncodings: ['quantitative', 'ordinal']` — the builder picks between them based on distinct-value count. This is a resolution of ambiguity already present in the type registry. The result is a concrete `FieldSemantics` with a single chosen encoding, a resolved domain, etc. - -2. **Instantiation time** (spec generation for a specific chart): The instantiation phase may **override** the context's resolved values based on the specific chart type, channel assignment, and visual constraints. For example: - - A `Coded` field with 30 values is resolved as `nominal` in the context. But when assigned to a color channel, the instantiator may decide to show only top-10 + "Other" to prevent legend clutter — this is a presentation decision, not a type-level one. - - A `Month` field resolved as `ordinal` in the context may be re-encoded as `temporal` if placed on X in a line chart — this is a chart-type-driven override. - - An ordinal field with high cardinality assigned to color may be treated as quantitative (continuous ramp) to reduce clutter — this is a channel-specific adaptation. - -**The boundary:** Context determination resolves *what the field IS* (its preferred encoding, format, domain, etc.). Instantiation resolves *how to render it given the chart constraints*. The context should carry enough information (including data statistics like cardinality) for the instantiator to make informed overrides without re-querying the type registry. - -```typescript -interface FieldSemantics { - // ... resolved dimension values ... - - // Data statistics carried forward for instantiation-time decisions - dataStats: { - cardinality: number; // distinct value count - nullRate: number; // fraction of nulls - min?: number; // for numeric fields - max?: number; - sortedDistinctValues?: string[]; // for ordinal/nominal (if small enough) - }; -} -``` - -This way, the instantiator can check `context.dataStats.cardinality` and decide to bin, filter, or re-encode — without the context itself making premature presentation decisions. - -### 0.8 Cyclic domain types - -A special class of types has **cyclic** (wrap-around) domains: - -| Type | Cycle | Values | Visualization concern | -|---|---|---|---| -| Month | 12 | Jan–Dec or 1–12 | Axis shouldn't show "13"; color interpolation wraps | -| Day (weekday) | 7 | Mon–Sun | Same | -| Hour | 24 | 0–23 | Circular charts natural | -| Direction | 8/16+ | N, NE, E, ... | Polar/radar natural | -| Quarter | 4 | Q1–Q4 | Axis ordering | - -Cyclic types need: -- Built-in canonical sort (not alphabetical) -- No extrapolation beyond the cycle -- Cyclic color palettes for color encoding -- Radar/polar chart recommendations - ---- - -## §1 Motivation - -### 1.1 Current state — Four-stage pipeline - -The chart engine uses a four-stage compilation pipeline, analogous to -LLVM's frontend → IR → middle-end → backend architecture: - -| Stage | Function | Input → Output | Concern | -|-------|----------|---------------|--------| -| **1.

These properties are **promoted** into a flat `ChannelSemantics` struct — the single public interface consumed by all downstream phases (VL assembler, ECharts assembler, recommendation engine, tooltip renderer). `FieldSemantics` itself is an internal type used only inside `resolveChannelSemantics()`. - -### 1.4 Non-goals - -- Changing Stage 3 (layout/stretch model) — it stays data-driven -- Building a full "smart defaults" system that replaces user configuration — the compilation context provides *defaults* that users and templates can override - -> **Note:** While §0 proposes adding new semantic types (Profit, Sentiment, NPS, etc.), the core taxonomy structure and string-based representation remain the same. The new types extend the existing catalog, they don't restructure it. - ---- - -## §2 Design Principles - -1. **Semantic type is the source of truth.** The compilation context is a deterministic function of (semanticType, dataValues, channel, markType). No hidden state. - -2. **Decisions are structured, not scattered.** Instead of N separate functions that each know about semantic types, one builder produces a typed context object. Downstream code reads fields, never re-inspects the semantic type. - -3. **Per-field, then per-channel.** Some decisions are intrinsic to the field (format, aggregation default, scale type) regardless of which channel it's mapped to. Others are channel-dependent (zero-baseline, reversed axis). The context has both layers. - -4. **Override-friendly.** Every decision has a default from the semantic type. Users, templates, or the AI agent can override any individual decision without replacing the whole context. Overrides are explicit and traceable. - -5. **Backend-agnostic.** The compilation context describes abstract visualization intent (e.g., "format as currency with 0 decimals", "reverse the axis"). Backend-specific translation (VL `axis.format` vs. ECharts `axisLabel.formatter`) happens in Stage 4 (spec generation). - -6. **Semantic type + optional metadata.** The semantic type string alone (e.g., `'Rating'`) is not always sufficient. Certain types carry additional properties (domain, unit) that are critical for correct visualization. This metadata is provided alongside the semantic type as a structured annotation. - ---- - -## §3 Semantic Type Annotation: Enriched Input - -### 3.1 The problem with bare semantic type strings - -Today, the LLM annotates each field with a single semantic type string: - -```json -{ "rating": { "type": "number", "semantic_type": "Rating" } } -``` - -But `Rating` alone is ambiguous: -- Is it 0–5? 1–5? 1–10? 0–100? -- Should we show exact tick marks [1, 2, 3, 4, 5] or let the renderer choose? -- Is 0 a valid value (meaningful zero) or is the scale 1-based (arbitrary zero)? - -Similar ambiguity exists for other bounded/scaled types: - -| Type | What's missing | Why it matters | -|---|---|---| -| **Rating** | Scale range (1–5, 1–10, 0–100) | Tick marks, domain constraint, zero decision | -| **Score** | Scale range (0–100, 0–10) | Same as Rating | -| **Percentage** | Representation (0–1 vs 0–100) | Format string: `.1%` vs `.1f` + "%" | -| **Temperature** | Unit (°C, °F, K) | Format suffix, diverging midpoint (0°C vs 32°F) | -| **Physical measures** (any) | Unit (kg, km, mph, etc.) | Format suffix | -| **Price/Revenue/Cost/Amount** | Currency (USD, EUR, GBP, JPY) | Format prefix ($, €, £, ¥) | -| **Duration** | Unit (seconds, minutes, hours, days) | Format strategy ("2h 30m" vs "150 min") | - -Notice this is NOT needed for open-ended measures like `Quantity`, `Count`, `Revenue` (generic), `Rank`, or categorical types like `Country`, `Status`. Those types have no inherent scale or unit ambiguity. - -### 3.2 SemanticAnnotation: the enriched input - -We extend the annotation format to carry optional metadata alongside the semantic type: - -```typescript -/** - * Enriched semantic annotation for a single field. - * - * The LLM (or user) provides this when annotating a dataset. - * Only `semanticType` is required — all other fields are optional - * hints that improve compilation decisions. - * - * Compact form: When no metadata is needed, a bare string is equivalent - * to `{ semanticType: "..."}`.

The context provides format information (pattern, prefix, suffix); the **renderer** decides how to use them — whether to put the unit on tick labels, in the axis title, or only in tooltips is a rendering concern, not a compilation concern. - -**Design principle — only override VL's native formatting when semantic context adds value.** - -VL's default axis formatting is excellent — it adapts precision, uses ~s notation for large values, and produces clean integer labels for integer data. We only provide an explicit format when: -- There's a **prefix** ($, €, +) or **suffix** (%, °C, kg) that VL can't know about -- There's an **abbreviation** need (1.2M instead of 1200000) -- There's a **sign** requirement (+12% / -5%) that VL won't add by default -- There's a **no-comma** override (Year: 2024 not 2,024) - -For generic decimal types (Number, Score, Rating, Ratio, Latitude, Longitude), the format is **empty** — VL handles axis formatting natively and does it better than any hardcoded precision. - -**Data-driven precision:** When format IS provided (currency, percent, unit-suffix, etc.), the precision is **data-driven** rather than hardcoded. The `detectPrecision()` helper examines actual data values and returns the maximum meaningful decimal places (0–4, capped to avoid floating-point noise). This means: -- Revenue data `[120000, 230000]` → `$120K, $230K` (0 decimals) -- Price data `[12.50, 8.99]` → `$12.50, $8.99` (2 decimals, always for Price) -- Temperature data `[23.5, 18.2]` → `23.5°C, 18.2°C` (1 decimal) - -| Semantic Type | `pattern` | `prefix` | `suffix` | `abbreviate` | Tooltip override | Notes | -|---|---|---|---|---|---|---| -| **Count** | `,d` | — | — | — | — | Integer with thousands sep | -| **Amount** | data-driven precision | `$` | — | yes | `,.2f` + prefix `$` | | -| **Price** | `,.2f` | `$` | — | yes | — | Always shows cents | -| **Revenue** | data-driven precision | `$` | — | yes | `,.2f` + prefix `$` | | -| **Cost** | data-driven precision | `$` | — | yes | `,.2f` + prefix `$` | | -| **Percentage** (0–1) | `.Xp%` | — | — | — | `.X+1p%` | Auto-detects 0–1 vs 0–100 | -| **Percentage** (0–100) | data-driven + `d`/`.Xf` | — | `%` | — | same | Suffix, no ×100 | -| **PercentageChange** | `+.X%` or `+.Xf` | — | `%` (if 0–100) | — | higher-precision | Always-show sign | -| **Temperature** | data-driven precision | — | from unit (`°C`) | — | higher-precision | Unit from annotation | -| **Score** | — (empty) | — | — | — | data-driven precision | VL handles axis natively | -| **Rating** | — (empty) | — | — | — | data-driven precision | VL handles axis natively | -| **Rank** | `,d` | — | — | — | — | Integer | -| **Year** | `d` | — | — | — | — | No comma (2024 not 2,024) | -| **Number** | — (empty) | — | — | — | data-driven precision | VL handles axis natively | -| **Quantity** | data-driven precision | — | from unit | yes | — | Unit from annotation | -| **Profit** | `+` + data-driven | `$` | — | yes | `+,.2f` + prefix `$` | Signed currency | -| **Sentiment** | `+` + data-driven | — | — | — | higher-precision | Signed decimal | -| **Correlation** | `+` + data-driven | — | — | — | higher-precision | Signed decimal | -| **Latitude, Longitude** | — (empty) | — | — | — | data-driven precision | VL handles axis natively | -| **Ratio** | — (empty) | — | — | — | data-driven precision | VL handles axis natively | - -**Unit and currency from annotation metadata:** When the LLM provides `unit` in the annotation (e.g., `"unit": "EUR"` for Price, `"unit": "kg"` for Weight), the format spec uses that directly. See §3 for the full annotation schema. - -**Fallback priority for units:** annotation.unit > column-name heuristics ("Weight (kg)") > data-value scanning ("$1,234") > type-specific defaults ("$" for Price). - -### 5.1.1 Parsing - -Parsing is the **compiler's responsibility**, not part of the compilation context. The semantic type already tells the compiler what the data represents — the compiler decides how to clean it. - -For example, knowing a field is `Amount` tells the compiler to strip `$` and `,` from `"$1,234.56"`. Knowing it's `Percentage` with string representation tells it to strip `%`. The semantic type + data representation (§3.5) provide all the information needed; no separate parse hint interface is required. - -**Semantic type as parsing guide:** - -| Semantic Type | Raw data examples | Compiler knows to... | -|---|---|---| -| Amount, Price, Revenue, Cost | `"$1,234.56"`, `"€1.234,56"` | Strip currency symbol + separators → number | -| Percentage, PercentageChange | `"45.2%"`, `"+12.3%"` | Strip `%` and sign → number | -| Temperature, Quantity (with unit) | `"23.5°C"`, `"75 kg"` | Strip unit suffix → number | -| Duration | `"2h 30m"`, `"02:30:00"` | Parse compound time → seconds | -| Timestamp | `1705312200`, `"2024-01-15"` | Detect epoch vs string → Date | -| Boolean | `"Yes"`, `"No"`, `1`, `0` | Normalize → boolean | -| Month | `"January"`, `1` | Normalize → canonical form | -| Coordinates | `"47°36'22"N"` | DMS → decimal degrees | - -The compiler may provide built-in parsing utilities internally, but that's an implementation detail — not something the compilation context needs to describe. - -### 5.2 Aggregation defaults - -| Semantic Family | Semantic Types | Default Aggregate | Rationale | -|---|---|---|---| -| **Additive measures** | Count, Amount, Revenue, Cost, Quantity, Duration | `sum` | These represent totals — summing is natural | -| **Intensive measures** | Percentage, PercentageChange, Temperature, Score, Rating, Price, Correlation, Sentiment | `average` | These represent rates/conditions — averaging is natural | -| **Signed additive** | Profit | `sum` | Additive but can be negative; summing preserves sign semantics | -| **Discrete numeric** | Rank, Index, ID | — (none) | Aggregation is meaningless | -| **Temporal** | DateTime, Date, Year, etc. | — (none) | Not aggregable | -| **Categorical** | Name, Status, Category, etc. | — (none) | Not aggregable | - -**When this helps:** When a bar chart is created with Revenue on Y, the system auto-applies `aggregate: 'sum'` (total revenue per category). For Temperature on Y, it auto-applies `aggregate: 'average'` (mean temperature per category). Currently, the AI agent or the user must specify this. - -### 5.3 Scale type recommendations - -| Condition | Recommended Scale | Example | -|---|---|---| -| Measure type + data spans >2 orders of magnitude | `log` | Revenue: $1K to $1B | -| Measure type + data has long tail (skew > 2) | `sqrt` | Population: most cities small, few very large | -| Measure type + data spans both positive and negative + wide range | `symlog` | Profit/Loss: -$10M to +$500M | -| Percentage (0-100) | `linear` (always) | Completion rate | -| All other quantitative | `linear` | Default | - -**Implementation note:** Scale type recommendation requires inspecting data distribution (min, max, skewness). This makes it a **data-dependent** decision that belongs in the compilation context builder, not in a static mapping. - -### 5.4 Domain constraints - -Domain constraints come from two sources: **annotation metadata** (explicit `intrinsicDomain` from the LLM) and **type-intrinsic knowledge** (geographic bounds, etc.). - -The effective domain stored in `FieldSemantics.domainConstraint` is always the **union** of the intrinsic domain and the actual data range. This ensures data points that exceed the type's natural bounds (e.g., 155% growth for a Percentage type) are never clipped. - -Two categories: - -- **Hard domains** (`clamp: true`): physically impossible to exceed — Latitude [-90, 90], Longitude [-180, 180], Correlation [-1, 1]. The intrinsic bounds _are_ the final bounds. -- **Soft domains** (`clamp: false`): intrinsic bounds describe the _typical_ range, but data can legitimately exceed them. Effective domain = `[min(intrinsic[0], dataMin), max(intrinsic[1], dataMax)]`. - -| Source | Semantic Type | Intrinsic Domain | Data Range | Effective Domain | Clamp? | -|---|---|---|---|---|---| -| **Annotation** | Rating (domain: [1, 5]) | [1, 5] | [1, 4] | `{ min: 1, max: 5 }` | soft | -| **Annotation** | Score (domain: [0, 100]) | [0, 100] | [0, 120] | `{ min: 0, max: 120 }` | soft | -| **Data-inferred** | Percentage (0–100 data) | [0, 100] | [0, 80] | `{ min: 0, max: 100 }` | soft | -| **Data-inferred** | Percentage (> 100 data) | [0, 100] | [0, 155] | `{ min: 0, max: 155 }` | soft | -| **Data-inferred** | Percentage (0–1 data) | [0, 1] | [0, 0.8] | `{ min: 0, max: 1 }` | soft | -| **Type-intrinsic** | Latitude | [-90, 90] | any | `{ min: -90, max: 90 }` | hard | -| **Type-intrinsic** | Longitude | [-180, 180] | any | `{ min: -180, max: 180 }` | hard | -| **Type-intrinsic** | Correlation | [-1, 1] | any | `{ min: -1, max: 1 }` | hard | - -**Priority:** annotation.intrinsicDomain > type-intrinsic > data-inferred. - -**Percentage scale detection:** The representation (0–1 fractional vs 0–100 whole-number) is detected from data: if ≥ 80% of absolute values are ≤ 1, treat as fractional; otherwise whole-number. This works even when values exceed the intrinsic range (e.g., [10, 20, 155] → whole-number → intrinsic [0, 100] → effective [0, 155]). - -When `annotation.intrinsicDomain` is provided, the builder also derives: -- **zeroBaseline:** If `intrinsicDomain[0] > 0` (e.g., Rating [1, 5]), zero is arbitrary. If `intrinsicDomain[0] === 0` (e.g., Score [0, 100]), zero is contextual. -- **tickConstraint:** If the intrinsic domain span is small (≤ 20), generate `exactTicks` for every integer. E.g., Rating [1, 5] → `exactTicks: [1, 2, 3, 4, 5]`. -- **binningSuggested:** If intrinsic domain span ≤ 20, binning is not useful → `false`. -- **colorSchemeHint.divergingMidpoint:** `(intrinsicDomain[0] + intrinsicDomain[1]) / 2`. E.g., Score [0, 100] → midpoint 50. - -### 5.5 Tick constraints - -Tick constraints combine type-intrinsic rules with annotation-provided domain: - -| Semantic Type | `integersOnly` | `exactTicks` | `minStep` | Source | -|---|---|---|---|---| -| Count | true | — | 1 | Type-intrinsic | -| Year | true | — | 1 | Type-intrinsic | -| Rank | true | — | 1 | Type-intrinsic | -| Rating (domain: [1, 5]) | true | [1, 2, 3, 4, 5] | 1 | Annotation domain | -| Rating (domain: [1, 10]) | true | [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] | 1 | Annotation domain | -| Score (domain: [0, 100]) | true | — (too many) | 1 | Annotation domain (span > 20 → no exactTicks) | -| Month (1-12) | true | [1..12] | 1 | Type-intrinsic | -| Index | true | — | 1 | Type-intrinsic | - -**Rule for exactTicks from annotation domain:** When `domain` is provided and `domain[1] - domain[0] ≤ 20`, generate integer ticks from `domain[0]` to `domain[1]`. When span > 20, use `integersOnly: true` with `minStep: 1` and let the renderer choose tick count. - -### 5.6 Reversed axis - -| Semantic Type | Reversed? | Rationale | -|---|---|---| -| Rank | `true` | 1st place should be at the top (Y axis) or leftmost (X axis) | -| All others | `false` | Standard direction | - -**Note:** Reversed axis is a *default suggestion*.

Define `SemanticAnnotation` interface in `types.ts` (see §3.2) -2. Add `normalizeAnnotation()` to accept both bare strings and enriched objects -3. Update `semantic_types` field type in `ChartAssemblyInput` to `Record` -4. Implement `resolveFieldSemantics()` in `field-semantics.ts` (Stage 1) -5. Implement all `resolve*()` sub-functions, with annotation.intrinsicDomain / annotation.unit flowing in -6. Add `FieldSemantics` to `types.ts` -7. Promote `FieldSemantics` properties into flat `ChannelSemantics` -8. In `resolveChannelSemantics` (Stage 2), call `resolveFieldSemantics` and promote properties into each channel - -**Phase A also includes updating the Python-side LLM prompt:** -9. Update `generate_semantic_types_prompt()` in `semantic_types.py` to request `intrinsic_domain` and `unit` for applicable types -10. Update `SYSTEM_PROMPT` in `agent_data_load.py` to show the enriched JSON format -11. Add backward-compatible parsing: accept both old `"Rating"` and new `{ "semantic_type": "Rating", "domain": [1, 5] }` formats - -**No existing behavior changes.** The context is computed but not yet consumed. - -### Phase B: Consume context in VL assembler (Stage 4) - -1. In `vlApplyLayoutToSpec`, read `cs.format` → apply `axis.format` -2. Read `cs.tickConstraint` → apply `axis.tickMinStep`, `axis.values` -3. Read `cs.reversed` → apply `scale.reverse` -4. Read `cs.domainConstraint` → apply `scale.domain` + `scale.clamp` -5. Read `cs.nice` → apply `scale.nice` - -**Existing zero/color/temporal/sort logic continues to work.** New properties layer on top. - -### Phase C: Consume context in ECharts assembler (Stage 4) - -Same as Phase B but translating to ECharts API (`axisLabel.formatter`, `yAxis.inverse`, etc.). - -### Phase D: Consume context in recommendation engine - -1. Use `cs.aggregationDefault` when auto-populating encodings -2. Use `cs.stackable` in stacked chart suitability checks -3. Use `cs.binningSuggested` in histogram recommendation - -### Phase E: Consolidate existing decisions - -1. `computeZeroDecision` reads `zeroBaseline` from `ChannelSemantics`; finalized in Stage 4 by each assembler -2. Move `getRecommendedColorScheme` to read from `cs.colorScheme` (promoted from FieldSemantics) -3. Move `inferOrdinalSortOrder` to read from `cs.ordinalSortOrder` (promoted from FieldSemantics) -4. Move temporal format resolution to `cs.temporalFormat` (promoted from FieldSemantics) - -After this phase, all semantic-type-driven decisions flow through the flat `ChannelSemantics` IR. No downstream code directly imports `isMeasureType()`, `isTimeSeriesType()`, etc. for decision-making. - ---- - -## §11 Open Questions - -1. **Unit/domain annotation reliability.** How reliably will the LLM provide `domain` and `unit`? Mitigation strategies: - - (a) Require domain/unit for a small set of types (Rating, Score, Temperature, Price) — reject annotations without them - - (b) Treat domain/unit as best-effort hints — fall back gracefully to data-inferred or type-intrinsic defaults (current proposal) - - (c) Prompt the user to confirm/correct LLM-provided annotations in certain cases - - Fallback priority: annotation.unit > column-name heuristics ("Weight (kg)") > data scan ("$1,234") > type defaults - - Note: `intrinsicDomain` replaces the old `domain` property for clarity - -2. **Scale type auto-detection.** Should we auto-switch to log scale when data spans >2 orders of magnitude? This is powerful but can surprise users. Options: - - (a) Never auto-switch; provide `scaleType` as a hint for recommendation only - - (b) Auto-switch with a prominent UI indicator ("Log scale applied") - - (c) Auto-switch only for specific types (Revenue, Population) where log is commonly expected - -3. **Reversed axis scope.** Rank reversal on Y makes sense, but what about X? A horizontal bump chart with rank on X should also reverse. Should `reversed` be axis-aware or axis-agnostic? - - Current proposal: axis-agnostic (template/backend decides how to apply) - -4. **Format vs. LLM context.** Should the compilation context's format information be passed to the LLM when generating chart code? This could help the LLM produce better Python/JS code that formats values correctly. But it adds token overhead. - -5. **Interaction with explicit user overrides.** When the user manually sets an axis format or domain, how does that interact with the compilation context? - - Proposed: User overrides always win. The context provides defaults; any explicit setting in `ChartEncoding` or `chartProperties` takes precedence. - -6. **Where does `resolveFieldSemantics` live?** *(Resolved)* - - Lives in `field-semantics.ts` (Option B) — clean separation; `semantic-types.ts` stays lean. - - Called internally by `resolveChannelSemantics()` in `resolve-semantics.ts` (Stage 2). - ---- - -## §12 Summary - -The compilation context is a structured bridge between semantic type knowledge and visualization property configuration. Instead of sprinkling `if (semanticType === 'Revenue') { ... }` across 6 files, we build a single typed context object per field and let all downstream consumers read from it. - -**What changes:** -- One new type: `SemanticAnnotation` (enriched input with optional `intrinsicDomain`, `unit`, `sortOrder`) -- One new type: `FieldSemantics` (structured output) -- One new builder: `resolveFieldSemantics(annotation, fieldName, values)` -- `ChannelSemantics` becomes flat — promotes field-semantics properties directly (no nested `fieldSemantics`) -- Dead properties removed: `aggregate`, `sortOrder`, `sortBy`, `typeReason` -- `semantic_types` map accepts both bare strings and annotation objects -- VL/ECharts assemblers gain a `vlApplyFieldContext()` step -- LLM prompts updated to request `intrinsic_domain`/`unit` for applicable types - -**What stays the same:** -- The semantic type string taxonomy -- The four-stage pipeline structure (Stage 1: Field Semantics → Stage 2: Channel Semantics → Stage 3: Layout → Stage 4: Spec Generation) -- The existing zero/color/temporal/sort decisions (they migrate to read from `ChannelSemantics`) -- The recommendation engine API - -**What's new:** -- Enriched semantic type annotation with optional `intrinsicDomain`, `unit`, and `sortOrder` metadata -- Field-aware formatting (axis ticks, tooltips, data labels) driven by annotation -- Aggregation defaults per semantic type -- Tick constraints (integer-only, exact ticks) -- Reversed axes for rank-like types -- Domain clamping for bounded types -- Scale type hints (log, sqrt) -- Interpolation hints for line charts -- Binning and stacking compatibility flags -- Diverging midpoint resolution from unit, type, intrinsicDomain, or data -- Cyclic domain support for wrap-around ordinals (seasons, compass directions) diff --git a/src/lib/agents-chart/docs/design-stretch-model.md b/src/lib/agents-chart/docs/design-stretch-model.md deleted file mode 100644 index 1a580a3d..00000000 --- a/src/lib/agents-chart/docs/design-stretch-model.md +++ /dev/null @@ -1,1029 +0,0 @@ -# Design: Axis Layout Compression - -> **Physics-based models for automatically sizing chart axes when data -> overflows the available canvas.** - -Four models cover the four geometric contexts in which layout pressure arises: - -| § | Model | Geometry | Chart types | -|---|---|---|---| -| [§1](#1-discrete-axis-elastic-budget-model) | Elastic Budget | 1D banded axis | Bar, Histogram, Heatmap, Boxplot | -| [§2](#2-continuous-axis-gas-pressure-model) | Gas Pressure | 2D point cloud | Scatter, Line, Area | -| [§3](#3-circumference-radial-pressure-model) | Circumference | 1D closed loop | Pie, Rose, Sunburst, Radar, Gauge | -| [§4](#4-area-layout-2d-pressure-model) | Area (2D) | 2D filled space | Treemap | - -All four share a common pattern: - -1. **Pressure = demand / supply.** Items need space; the base canvas provides it.

This depends on two independent properties: - -1. **Scale type** — the Vega-Lite encoding type of the field. -2. **Mark geometry** — whether the mark occupies a fixed-width band or a point-like position. - -### Banded layout - -A **banded** axis allocates a fixed-width slot (band) per data position. The layout model controls the step size per slot. Items are read by the width/area of their band. - -| Condition | Example | -|---|---| -| **Discrete scale** (nominal / ordinal) | Categories on a bar chart, ordinal months | -| **Continuous scale + band mark** | Bar chart with quantitative or temporal X (years as numbers) | -| **Binned axis** (`bin: true`) | Histogram bins — each bin is a band regardless of scale | - -### Non-banded layout - -A **non-banded** axis places items at data-determined positions within a continuous range. The layout model controls the overall canvas size but does **not** allocate per-item slots. - -| Condition | Example | -|---|---| -| **Continuous scale + point mark** | Scatter plot, line chart, area chart | - -### Summary matrix - -| | Band mark (bar, rect, boxplot) | Point mark (circle, line, area) | -|---|---|---| -| **Discrete scale** (N/O) | Banded — §1 | Banded — §1 (*) | -| **Continuous scale** (Q/T) | Banded — §1 | Non-banded — §2 | - -(*) Discrete scales are always banded regardless of mark type — VL allocates a band per category. - -## §0.2 Decision Tree - -``` -For each positional axis (x, y): - -1.

We handle this in two phases: - -**Phase 1 — Canvas sizing (assemble.ts):** - -``` -continuousWidth = stepSize × (N + 1) -``` - -The `+1` adds half-step padding on each side. The scale domain is extended by ±halfStep so positions align as they would on a discrete band scale. - -**Phase 2 — Mark sizing (postProcessing):** - -Since VL won't auto-size bars on a continuous scale: -1.

Each item ideally occupies $\ell_0$ pixels (the natural length). When $N \cdot \ell_0 > L_0$, the items overflow. - -Two competing goals must be balanced: - -1. **Items resist compression** — each item pushes outward to maintain $\ell_0$, and cannot shrink below $\ell_{\min}$. -2. **The axis resists expansion** — the axis can stretch beyond $L_0$ but has a hard maximum $L_{\max}$. - -## §1.2 Parameters - -| Symbol | Meaning | Code mapping | Default | -|---|---|---|---| -| $L_0$ | Natural axis length | `width` / `height` (canvas size) | 400 px | -| $L_{\max}$ | Maximum axis length | `width × maxStretch` | 800 px | -| $N$ | Number of banded items | Field cardinality | data-dependent | -| $\ell_0$ | Natural length per item | `defaultStepSize` | ~20 px | -| $\ell_{\min}$ | Minimum length per item | `minStep` option | 6 px | -| $\alpha$ | Elasticity exponent | `elasticity` option | 0.5 | -| $\beta$ | Maximum stretch multiplier | `maxStretch` option | 2.0 | - -> **Code defaults:** `ElasticStretchParams` in `core/decisions.ts` — `elasticity: 0.5`, `maxStretch: 2`, `minStep: 6`. The `defaultStepSize` is computed dynamically based on canvas size: `round(20 × max(1, sizeRatio) × defaultStepMultiplier)`. - -## §1.3 Three Regimes - -### Regime 1: No compression needed - -**Condition:** $N \cdot \ell_0 \leq L_0$ - -All items fit at their natural length: - -$$\ell = \ell_0, \quad L = N \cdot \ell_0$$ - -### Regime 2: Overflow beyond recovery - -**Condition:** $N \cdot \ell_{\min} \geq L_{\max}$ - -Even at minimum item length and maximum stretch, not all items fit. Excess items are truncated: - -$$N' = \left\lfloor \frac{L_{\max}}{\ell_{\min}} \right\rfloor, \quad \ell = \ell_{\min}, \quad L = L_{\max}$$ - -### Regime 3: Elastic equilibrium - -**Condition:** $N \cdot \ell_0 > L_0$ and $N \cdot \ell_{\min} < L_{\max}$ - -Items overflow but can be accommodated by compressing items and/or stretching the axis. This is where the elastic model applies. - -## §1.4 Power-Law Elastic Budget - -This is the **implemented model**. The axis stretches using a power-law of the pressure ratio: - -**Pressure:** - -$$p = \frac{N \cdot \ell_0}{L_0}$$ - -**Stretch factor:** - -$$s = \min(\beta,\; p^{\alpha})$$ - -**Resulting step size:** - -$$\ell = \frac{L_0 \cdot s}{N} = \frac{L_0 \cdot p^{\alpha}}{N}$$ - -With $\alpha = 0.5$, doubling the overflow only increases the stretch by $\sqrt{2} \approx 1.41\times$ — a naturally progressive response. - -**Clamping:** The step is clamped to $[\ell_{\min},\; \ell_0]$ and the axis length to $[L_0,\; L_{\max}]$. - -> **Implementation:** `computeElasticBudget()` in `core/decisions.ts` (lines ~549–569). Called by `computeAxisStep()` which handles both nominal and continuous-as-discrete cases. - -## §1.5 Linear Spring Model (Theoretical Foundation) - -The power-law model can be motivated by a physical analogy: $N$ identical springs packed inside a box. - -**Setup:** -- Each spring (item) has natural length $\ell_0$, solid length $\ell_{\min}$, spring constant $k_1$. -- The box (axis) has natural length $L_0$, max length $L_{\max}$, spring constant $k_2$. - -**Force balance at equilibrium:** - -$$N \cdot k_1 \cdot (\ell_0 - \ell) = k_2 \cdot (N \cdot \ell - L_0)$$ - -**Equilibrium step size** (using stiffness ratio $\kappa = k_1 / k_2$): - -$$\boxed{\ell = \frac{\kappa \cdot \ell_0 + L_0 / N}{1 + \kappa}}$$ - -**Interpretation of $\kappa$:** -- $\kappa \to \infty$: items don't compress; the wall absorbs everything ($\ell \to \ell_0$). -- $\kappa \to 0$: items compress to fit the fixed axis ($\ell \to L_0 / N$). -- $\kappa = 1$: compression is split evenly ($\ell = (\ell_0 + L_0/N) / 2$). - -The linear spring model is more physically intuitive and allows independent tuning of item vs. wall stiffness ($\kappa$). It is presented here as the theoretical motivation for the power-law model. - -**Nonlinear (progressive-rate) variant:** Replacing the linear spring with a hardening spring $F_1(\ell) = k_1 \cdot ((\ell_0 - \ell) / (\ell_0 - \ell_{\min}))^{\gamma}$ leads directly to the power-law formulation used in the implementation. - -## §1.6 Relationship Between Formulations - -| Linear spring model | Power-law implementation | -|---|---| -| $\kappa$ (stiffness ratio $k_1/k_2$) | $\alpha$ (elasticity exponent) | -| $\ell = (\kappa \cdot \ell_0 + L_0/N) / (1 + \kappa)$ | $s = \min(\beta, p^{\alpha})$; $\ell = L_0 \cdot s / N$ | -| Uniform interpolation between $\ell_0$ and $L_0/N$ | Power-curve interpolation favoring $\ell_0$ | -| Two parameters ($k_1$, $k_2$) | One parameter ($\alpha$) | -| More physically intuitive | More compact; naturally progressive | - -## §1.7 Grouped Items - -Grouped items (e.g., grouped bar with $m$ sub-bars per group) are treated as a special case — the **group** is the unit of compression, not the individual item. - -| Parameter | Simple discrete | Grouped bar ($m$ sub-bars) | -|---|---|---| -| $\ell_0$ (natural) | `defaultStepSize` | $m \times$ `defaultStepSize` | -| $\ell_{\min}$ (solid) | `minStep` (6 px) | $2m$ px (2 px per sub-bar) | -| $N$ (item count) | Field cardinality | Number of **groups** | - -The elastic budget formula is unchanged — only the parameter values change. - -**Example:** 15 groups × 3 sub-bars on a 400 px axis: -- $N = 15$, $\ell_0 = 60$, ideal $= 900 > 400$ → Regime 3. -- With $\alpha = 0.5$: $p = 900/400 = 2.25$, $s = \min(2, 2.25^{0.5}) = 1.50$. -- Budget $= 400 \times 1.5 = 600$, step $= 600/15 = 40$ px per group. - -> **Implementation:** In `computeLayout()`, grouping is detected via the `group` channel. When `xHasGrouping` is true, step is computed per-group with `xStepUnit = 'group'` and a minimum group gap of 3 px is enforced. - -## §1.8 Per-Mark-Type Guidelines - -Different mark types have different visual footprints and compression tolerances. Templates can tune behavior via `defaultStepMultiplier` and `overrideDefaultSettings`. - -**Design guidelines** (for a 300 px reference canvas, `defaultStepSize` ≈ 20 px): - -| Mark type | $\ell_0$ | $\ell_{\min}$ | Compression tolerance | Rationale | -|---|---|---|---|---| -| **Bar** | 20 px | 6 px | Moderate | Width encodes the item — can't shrink too much | -| **Stacked bar** | 20 px | 6 px | Low | Stacked segments unreadable when thin | -| **Grouped bar** ($m$) | $20m$ px | $2m$ px | Low | Losing sub-bar distinction is costly | -| **Lollipop** | 14 px | 4 px | High | Dot (position) carries encoding, not width | -| **Heatmap / rect** | 20 px | 8 px | Very low | Color cell needs area for color to be perceivable | -| **Boxplot** | 24 px | 10 px | Low | Internal structure (box/whiskers/median) lost early | -| **Strip / jitter** | 24 px | 6 px | Moderate | Points collapse into a line when too narrow | -| **Histogram** | 16 px | 4 px | High | Distribution shape survives compression well | -| **Candlestick** | 18 px | 8 px | Low | Open/close body + wicks need room | - -**Design principles:** -1. Marks encoding value by **width/area** (bar, rect) → higher $\ell_0$, lower compression tolerance. -2. Marks encoding value by **position** (lollipop, bump) → higher compression tolerance. -3. Marks with **internal structure** (boxplot, candlestick) → higher $\ell_{\min}$. -4. Marks showing **distribution shape** (histogram) → can be narrower. - -> **Note:** Currently, templates primarily adjust layout via `defaultStepMultiplier` (scales $\ell_0$ proportionally) and `overrideDefaultSettings`. Per-mark-type spring stiffness ($\kappa$) is a design aspiration, not yet individually parameterized in the code. - -## §1.9 Faceted Charts - -Faceting splits one chart into a grid of subplots. This introduces an additional layer of layout compression: the canvas must accommodate $F$ panels, each containing its own axis. - -### §1.9.1 Facet stretch factor - -The total canvas stretches to accommodate facets: - -$$\lambda_f = \min(\beta,\; F^{\alpha_f})$$ - -where $\alpha_f$ = `facetElasticity` (default 0.3) and $\beta$ = `maxStretch` (default 2.0). - -The facet stretch uses a **gentler exponent** ($\alpha_f = 0.3$ vs $\alpha = 0.5$ for discrete items) because each subplot is a self-contained chart — even a small subplot can be readable, whereas a 3 px bar cannot. - -> **Implementation:** `computeLayout()` lines ~256–270 in `compute-layout.ts`. Uses `facetElasticityVal = 0.3` and `maxStretchVal = 2`. - -### §1.9.2 Subplot sizing - -Each subplot gets a share of the stretched canvas: - -$$W_{\text{sub}} = \max\!\left(S_{\min},\; \frac{W_0 \cdot \lambda_f - \text{fixedPad}}{F_c} - \text{gap}\right)$$ - -| Symbol | Meaning | Default | -|---|---|---| -| $F_c, F_r$ | Facet columns / rows | data-dependent | -| $\alpha_f$ | Facet elasticity | 0.3 | -| $S_{\min}$ | Minimum subplot size (continuous axis) | 60 px | - -### §1.9.3 Facet-mode shrink limits - -Under faceting, axes can shrink **further** than in single-chart mode because the reader compares patterns across panels rather than reading individual values precisely. - -| Mark type | $\ell_{\min}^{f}$ (banded) | $S_{\min}$ (continuous) | -|---|---|---| -| Bar / stacked bar | 3 px | 60 px | -| Heatmap / rect | 4 px | 40 px | -| Boxplot | 6 px | 60 px | -| Line / area | — | 40 px | -| Ridge / density | — | 20 px | -| Scatter | — | 60 px | - -### §1.9.4 Faceted discrete axis - -The spring model runs **per subplot**: $W_{\text{sub}}$ becomes $L_0$ and $N_{\text{items}}$ is the per-panel count. If items still overflow, they are truncated to $N' = \lfloor W_{\text{sub}} / \ell_{\min} \rfloor$. - -### §1.9.5 Faceted continuous axis - -The gas pressure model (§2) runs within each subplot using $W_{\text{sub}} \times H_{\text{sub}}$ as the container. Subplot dimensions are uniform across panels for visual consistency. - -### §1.9.6 Facet wrap (column-only folding) - -When only a column facet is specified and $F$ exceeds the maximum columns that fit, panels wrap into a 2D grid: - -1. **Maximum columns:** $F_{c,\max} = \lfloor \text{effectiveW} / (S_{\min} + \text{gap}) \rfloor$, where $\text{effectiveW} = W_0 \times \beta - \text{fixPad}$. -2. **Single row:** If $F \leq F_{c,\max}$, all panels fit in one row. No wrapping. -3. **Wrapping:** Otherwise, start with $F_c = F_{c,\max}$ columns and compute $F_r = \lceil F / F_c \rceil$ rows. -4. **Widow avoidance:** If the last row would contain exactly 1 panel (a "widow"), reduce $F_c$ by 1 and recompute. Repeat while $F_c > 2$ and widow exists. This redistributes panels more evenly — e.g., 11 panels with maxCols=5 → 5×3 would leave 1 orphan, so try 4×3 (last row has 3). - -The minimum subplot size ($S_{\min}$) is axis-aware: -- **Discrete/banded axes:** $S_{\min} = \ell_{\min} \times N$ (minStep × value count per axis). -- **Continuous axes:** $S_{\min} = \text{baseMinSubplot}$ (default 60 px), adjusted by banking AR when both axes are continuous — the shorter dimension stays at base, the longer gets up to $\beta \times$ base. This ensures line charts (landscape AR) get wider min subplots, producing fewer wider panels. - -> **Implementation:** `computeFacetGrid()` in `compute-layout.ts`. Runs **before** `computeLayout()` to break the circularity between wrapping and axis sizing. - -## §1.10 Summary - -| Symbol | Meaning | Default | -|---|---|---| -| $N$ | Number of discrete items | data-dependent | -| $\ell_0$ | Natural step size | ~20 px | -| $\ell_{\min}$ | Minimum step size | 6 px | -| $\alpha$ | Elasticity exponent | 0.5 | -| $\beta$ | Maximum stretch | 2.0 | - -``` -Given: N items, natural length ℓ₀, solid length ℓ_min, - axis rest length L₀, maxStretch β, elasticity α - -pressure = N · ℓ₀ / L₀ - -if pressure ≤ 1: - ℓ = ℓ₀ # Regime 1: fits - -elif N · ℓ_min ≥ β · L₀: - ℓ = ℓ_min, truncate to N' items # Regime 2: overflow - -else: - stretch = min(β, pressure^α) # Regime 3: elastic - ℓ = L₀ · stretch / N - ℓ = clamp(ℓ, ℓ_min, ℓ₀) -``` - -> **Key functions:** `computeElasticBudget()`, `computeAxisStep()` in `core/decisions.ts`; `computeLayout()` in `core/compute-layout.ts`. - ---- - -# §2 Continuous Axis (Gas Pressure Model) - -## §2.1 Problem - -A continuous axis displays $N$ point-like items (scatter dots, line vertices) across a 2D canvas. Unlike discrete items, these marks do not occupy fixed bands — they float at data-determined positions. Each mark has a visual cross-section $\sigma$ (px²). - -**Why springs don't apply:** Continuous marks don't own slots. A scatter plot with 100 points and one with 10 can both fit in the same canvas — the difference is **density**, not per-item allocation. This is the domain of gas physics. - -## §2.2 Parameters - -| Symbol | Meaning | Code mapping | Default | -|---|---|---|---| -| $W_0, H_0$ | Natural canvas dimensions | `subplotWidth`, `subplotHeight` | 400 × 320 px | -| $\sigma$ | Mark cross-section (px²) | `markCrossSection` | 30 px² | -| $\sigma_x, \sigma_y$ | Per-axis cross-sections | `markCrossSectionX/Y` | chart-type specific | -| $\alpha_c$ | Elasticity exponent | `elasticity` | 0.3 | -| $\beta_c$ | Maximum stretch | `maxStretch` | 1.5 | - -> **Code defaults:** `DEFAULT_GAS_PRESSURE_PARAMS` in `core/decisions.ts` — `markCrossSection: 30`, `elasticity: 0.3`, `maxStretch: 1.5`. - -**Why $\beta_c$ is smaller than discrete $\beta$:** Continuous axes encode by **position along a scale** — the most perceptually robust channel (Cleveland & McGill, 1984). A scatter plot remains readable even when compressed because relative positions are preserved. Discrete axes encode by **length/area of bands**, which degrades faster. - -| | Discrete axis | Continuous axis | -|---|---|---| -| Primary encoding | Length / area of band | Position along scale | -| Recommended $\beta$ | 2.0 | 1.5 | - -## §2.3 Per-Axis Stretch - -Crowding is almost always asymmetric — e.g., on a line chart, X is driven by time points while Y is driven by overlapping series. Each axis is stretched independently. - -### Mode 1: Positional (default) - -Count unique pixel positions along the axis (bucketed at ~1 px resolution).

The 2D path (both axes continuous) and 1D path (one axis continuous) are handled separately in `computeLayout()` lines ~275–425. - -## §2.4 Positional ≥ Series Constraint - -For charts where both axes are continuous (line, area), more series means more visual clutter on the **positional** axis too — more overlapping lines means more crossings and parallel strokes competing for the reader's attention. The positional axis ideal stretch is lifted to at least the series axis ideal stretch: - -$$\text{ideal}_{\text{positional}} = \max(\text{ideal}_{\text{positional}},\; \text{ideal}_{\text{series}})$$ - -When `maintainContinuousAxisRatio` is set, both axes use the maximum of the two stretches. - -## §2.5 Parameter Table - -| Chart type | $\sigma_x$ | $\sigma_y$ | $\alpha_c$ | $\beta_c$ | seriesCountAxis | -|---|---|---|---|---|---| -| Scatter | 30 | 30 | 0.3 | 1.5 | — | -| Line | 100 | 20 | 0.3 | 1.5 | auto (→ Y) | -| Area | 100 | 20 | 0.3 | 1.5 | auto (→ Y) | -| Streamgraph | 100 | 20 | 0.3 | 1.5 | auto (→ Y) | -| Bump | 80 | 20 | 0.3 | 1.5 | auto (→ Y) | -| Stacked Bar | 20 | 20 | 0.3 | 1.5 | auto (→ Y*) | - -\* For stacked bar, X is discrete (§1), Y is continuous. `auto` resolves to Y via the 1D path. - -## §2.6 Worked Examples - -### Series-axis stretch ($\sigma = 20$, $\text{dim}_0 = 300$, $\alpha_c = 0.3$, $\beta_c = 1.5$) - -| Scenario | nSeries | pressure | stretch | Final dim | -|---|---|---|---|---| -| 8 series (typical) | 8 | 0.53 | 1.0 | 300 | -| 15 series (moderate) | 15 | 1.0 | 1.0 | 300 | -| 20 series (busy) | 20 | 1.33 | 1.09 | 328 | -| 40 series (extreme) | 40 | 2.67 | 1.35 | 406 | - -### Combined positional + series (positional ≥ series constraint) - -| Scenario | nDates | nSeries | raw X | raw Y | final X | final Y | -|---|---|---|---|---|---|---| -| 12 dates × 20 series | 12 | 20 | 1.0 | 1.09 | **1.09** | 1.09 | -| 100 dates × 40 series | 100 | 40 | 1.32 | 1.35 | **1.35** | 1.35 | -| 100 dates × 60 series | 100 | 60 | 1.32 | 1.50 | **1.50** | 1.50 | -| 200 dates × 3 series | 200 | 3 | 1.50 | 1.0 | 1.50 | 1.0 | -| 200 dates × 20 series | 200 | 20 | 1.50 | 1.09 | 1.50 | 1.09 | - -## §2.7 Summary - -| Symbol | Meaning | Default | -|---|---|---| -| $\sigma$ | 2D mark cross-section (px²) | 30 | -| $\sigma_{1d}$ | 1D projection: $\sqrt{\sigma}$ | ~5.5 | -| $\alpha_c$ | Elasticity exponent | 0.3 | -| $\beta_c$ | Max stretch | 1.5 | - -``` -Given: data points with x/y values, per-axis cross-sections σ_x σ_y, - canvas W₀×H₀, elasticity αc, maxStretch βc, - optional seriesCountAxis - -For each axis (X, Y): - if seriesCountAxis resolves to this axis: - nSeries = |distinct color ∪ detail values| - pressure = nSeries · σ / dim₀ - else: - uniquePos = |{ round(v · px_per_unit) : v ∈ data }| - σ_1d = √σ - pressure = uniquePos · σ_1d / dim₀ - - if pressure ≤ 1: - stretch = 1 - else: - stretch = min(βc, pressure^αc) - -# Positional ≥ Series constraint (when seriesCountAxis is set): -stretch_positional = max(stretch_positional, stretch_series) - -W = W₀ · stretch_x -H = H₀ · stretch_y -``` - -> **Key functions:** `computeGasPressure()` in `core/decisions.ts`; gas-pressure integration in `computeLayout()` in `core/compute-layout.ts`. - -## §2.8 Faceted Continuous Layout (Per-Subplot Baseline → Pressure → AR Blend → Fit) - -### §2.8.1 Problem - -When faceted, the gas pressure model must answer: **what canvas does each subplot's data crowd against?** - -Naive approach: run gas pressure against the full canvas, then divide by column/row count. This over-estimates available space — each subplot only gets a fraction. Sub-plots end up too large, exceeding the total budget. - -Alternative naive approach: divide the raw canvas by column/row count first, then run gas pressure per-subplot. This under-estimates — it ignores the facet stretch the layout engine will apply, so gas pressure sees an artificially tiny canvas and immediately saturates. - -The correct answer is: **gas pressure runs against the per-subplot canvas that already accounts for facet elasticity** — the same stretch formula used for discrete axes. - -### §2.8.2 Per-Subplot Baseline Canvas - -Before gas pressure runs, we compute what each subplot would get from facet stretch alone: - -$$W_{\text{sub}} = \max\!\left(S_{\min},\; \frac{W_0 \cdot \lambda_f - \text{fixPad}}{F_c} - \text{gap}\right)$$ - -where $\lambda_f = \min(\beta,\; F_c^{\,\alpha_f})$ is the facet elasticity stretch (§1.9.1). For a single-panel chart ($F_c = 1$), $W_{\text{sub}} = W_0$. - -This gives gas pressure a realistic baseline: the space the subplot will actually occupy before any gas-pressure-driven stretch. - -> **Implementation:** `perSubplotCanvasW/H` in `computeLayout()` (~line 410–420). Uses `facetElasticityVal = 0.3` and `maxStretchVal = 2`. - -### §2.8.3 Banking AR (Multi-Scale Slope Optimization) - -For charts with connected marks (line, area, streamgraph), the data has a **perceptually optimal aspect ratio** determined by the slopes of the line segments. This is the *banking to 45°* principle (Cleveland, 1993): the chart should be shaped so that the median line segment slope approaches 45°, making trends maximally visible. - -We use a **multi-scale banking** approach (Heer & Agrawala, 2006) that considers slopes at multiple smoothing levels: - -**Algorithm:** - -1. **Group by series** (color ∪ detail fields). Sort each series by X. -2. **For each scale** $k = 0, 1, 2, \ldots$ (window size $= 2^k$): - - Smooth each series with non-overlapping box filters of width $2^k$. - - Compute absolute slopes between consecutive smoothed points: $|s| = |\Delta y / \Delta x|$ (in normalized data coordinates). - - Take the **median** absolute slope at this scale. -3. **Combine** per-scale medians via geometric mean: - $$\text{combinedSlope} = \exp\!\left(\frac{1}{K}\sum_{k=0}^{K}\ln(\text{median}_k)\right)$$ -4. **Clamp** to $[0.5,\; 3.0]$. -5. **Landscape floor** (connected marks only): $\text{AR} = \max(1.0,\; \text{combinedSlope})$. Time series are conventionally landscape; banking should push wider (when slopes are steep) but never portrait — the gentle-slope majority in typical time series would otherwise dominate the median and produce portrait, compressing the time axis. - -**For scatter plots** (non-connected): Instead of line slopes, use the standard-deviation ratio $\sigma_x / \sigma_y$ in normalized coordinates, with a dampened response: $\text{AR} = 1 + 0.3 \times (\text{sdRatio} - 1)$. - -**No dampening.** The raw combined slope is returned without any multiplicative dampening. The 50/50 blend with gas pressure (§2.8.4) is the sole moderation — applying dampening on top would double-moderate. - -> **Implementation:** `computeBankingAR()` in `compute-layout.ts` (~line 819). Returns W/H aspect ratio in $[0.5,\; 3.0]$. - -### §2.8.4 Gas–Banking AR Blend - -Gas pressure knows which axis is more crowded (density asymmetry). Banking knows the perceptual ideal AR (slope optimization). We blend both signals in **log space** with equal weight: - -$$\text{gasAR} = \frac{\text{rawW}}{\text{rawH}} \qquad \text{(from gas pressure per-axis stretches)}$$ - -$$\text{blendedAR} = \exp\!\left(0.5 \cdot \ln(\text{gasAR}) + 0.5 \cdot \ln(\text{bankingAR})\right)$$ - -This is the geometric mean: if gas pressure says 2:1 (X crowded) and banking says 1:1 (slopes are gentle), the blend yields $\sqrt{2} \approx 1.41$. - -**Coverage gate:** Banking is only applied when both X and Y data cover at least 20% of their respective domains. When data is concentrated in a small region (e.g., a cluster in one corner), slopes are unreliable and gas pressure alone drives the AR. - -### §2.8.5 Area Budget and Shape - -The blend decides the AR; gas pressure decides the total area: - -$$\text{rawArea} = \text{rawW} \times \text{rawH}$$ - -Capped to prevent the subplot from exceeding its per-subplot budget before the fit step: - -$$\text{area} = \min(\text{rawArea},\; W_{\text{sub}} \times H_{\text{sub}} \times \beta)$$ - -Distribute area to match the blended AR: - -$$\text{idealW} = \sqrt{\text{area} \times \text{blendedAR}} \qquad \text{idealH} = \sqrt{\text{area} / \text{blendedAR}}$$ - -### §2.8.6 Fit to Budget (Preserving AR) - -Hard ceiling per subplot: $W_0 \times \beta$ total, shared across facet panels: - -$$\text{availW} = \frac{W_0 \cdot \beta - \text{fixPad}}{F_c} - \text{gap} \qquad \text{availH} = \frac{H_0 \cdot \beta - \text{fixPad}}{F_r} - \text{gap}$$ - -Scale down uniformly to preserve the blended AR: - -$$\text{fitScale} = \min\!\left(\frac{\text{availW}}{\text{idealW}},\; \frac{\text{availH}}{\text{idealH}},\; 1\right)$$ - -$$\text{finalW} = \max(S_{\min},\; \text{idealW} \times \text{fitScale}) \qquad \text{finalH} = \max(S_{\min},\; \text{idealH} \times \text{fitScale})$$ - -The uniform `fitScale` ensures neither axis exceeds its budget AND the blended AR is preserved (except at minimum-size extremes). - -### §2.8.7 Worked Example - -150 dates × 8 series × 3 column facets (base $400 \times 300$, $\beta = 2.0$, line chart: $\sigma_x = 100$, $\sigma_y = 20$, `seriesCountAxis: auto → Y`, `facetElasticity = 0.3`): - -**Per-subplot baseline:** -- Facet stretch: $\lambda_f = \min(2, 3^{0.3}) = 1.35$ -- $W_{\text{sub}} = (400 \times 1.35) / 3 = 180$ px - -**Gas pressure** (against $180 \times 300$): -- X positional: 150 unique, $\sigma_{1d} = 10$ → $p = 8.33$ → raw stretch $= 8.33^{0.3} = 1.93$ -- Y series: 8 series, $\sigma = 20$ → $p = 0.53$ → raw stretch $= 1.0$ -- rawW $= 180 \times 1.93 = 347$, rawH $= 300 \times 1.0 = 300$, gasAR $= 1.16$ - -**Banking AR** (multi-scale slopes): Suppose combinedSlope yields bankingAR $= 1.8$ (landscape). - -**Blend:** $\text{blendedAR} = \exp(0.5 \ln 1.16 + 0.5 \ln 1.8) = \sqrt{1.16 \times 1.8} = 1.44$ - -**Area:** rawArea $= 347 \times 300 = 104{,}100$. maxArea $= 180 \times 300 \times 2 = 108{,}000$. area $= 104{,}100$. -- idealW $= \sqrt{104100 \times 1.44} = 387$, idealH $= \sqrt{104100 / 1.44} = 269$ - -**Fit:** availW $= (800 - 0) / 3 = 267$, availH $= 600$. -- fitScale $= \min(267/387, 600/269, 1) = 0.69$ -- finalW $= 387 \times 0.69 = 267$, finalH $= 269 \times 0.69 = 186$ -- **Final: 267 × 186, AR = 1.44** ✓ landscape preserved, total width = 800 - -> **Implementation:** `computeLayout()` in `core/compute-layout.ts` — the cont×cont path (~lines 370–530). `computeBankingAR()` (~line 819). `computeGasPressure()` in `core/decisions.ts`. - -## §2.9 Band AR Blending - -### §2.9.1 Problem - -When one axis is banded (discrete) and the other is continuous — e.g., a bar chart with categories on X and values on Y — the step size from §1 determines the band width, while the continuous axis uses the default canvas height. If there are few categories with a tall canvas, each band becomes excessively elongated (tall, thin bars). This degrades readability: labels crowd, bar proportions look distorted, and the chart wastes vertical space. - -### §2.9.2 Target Band AR - -The **band aspect ratio** is the ratio of the continuous dimension to the step size: - -$$\text{bandAR} = \frac{\text{continuousDim}}{\text{stepSize}}$$ - -When `bandAR` is large (e.g., 20:1), each bar is 20× taller than it is wide — visually extreme. A `targetBandAR` parameter (default: 10) defines the maximum acceptable ratio. - -### §2.9.3 Log-Space Blend - -When the actual band AR exceeds the target, the continuous axis is **shrunk** toward the ideal via a 50/50 log-space blend (same mechanism as §2.8.4): - -$$\text{idealDim} = \text{stepSize} \times \text{targetBandAR}$$ - -$$\text{blendedDim} = \exp\!\left(0.5 \cdot \ln(\text{actualDim}) + 0.5 \cdot \ln(\text{idealDim})\right)$$ - -The result is clamped to $[S_{\min},\; \text{actualDim}]$ — the blend only **shrinks**, never grows.

The relevant dimension is the **circumference**. When many items crowd the circumference, the chart must grow to keep slices/spokes legible. - -**Why axis models don't apply:** -- **§1 (Spring):** Assumes a 1D axis with endpoints. Radial charts have a closed loop — growing means increasing the **radius**, which increases circumference as $C = 2\pi r$. -- **§2 (Gas):** Assumes 2D free-floating points.

Edge cases: binary categories, legend overflow, huge value ranges. - -### How to add a test - -Add one row to `SCATTER_MATRIX` in `scatter-tests.ts`: - -```typescript -{ x: 'N', y: 'Q', n: 40, xCard: 8, color: 'Q', desc: 'Strip + continuous color, moderate density' }, -``` - -The generator handles field naming, data synthesis, metadata, tags, and title automatically. - ---- - -## Line Chart - -A line chart connects data points with lines. Lines imply sequential progression, so axes use T (temporal), O (ordinal), or Q (quantitative) — never purely nominal. N (nominal) is used only for color groups. - -Channels: `x, y, color, opacity, column, row` - -### Matrix-driven approach - -Tests are generated from `LINE_MATRIX` in `line-tests.ts`.

Each row is an independent event, not a sequential series; lines connect points in data order producing random zig-zags. Better served by scatter or dumbbell charts. -- **O×O** — ordinal×ordinal lines are degenerate. -- **N×N, T×N, N×T** — purely nominal axes don't suit line charts. Lines imply sequence/progression; connecting unordered categories is misleading. - -### Coverage summary - -Axis combos: T×Q, O×Q, Q×Q, Q×O. Color variants (N, Q) crossed with primary combos. Density from 5 to 4000 (stress). Sparse dropout tests irregular gaps. Total **16 tests**. - ---- - -## Bar Chart / Stacked Bar Chart / Grouped Bar Chart - -Bar charts encode values as rectangular bars. Three variants share a common matrix format in `bar-tests.ts`: -- **Bar Chart**: `x, y, color, opacity` — basic bars with optional color -- **Stacked Bar Chart**: `x, y, color` — bars stacked by color dimension -- **Grouped Bar Chart**: `x, y, group` — bars side-by-side by group dimension - -### Matrix-driven approach - -Three matrices (`BAR_MATRIX`, `STACKED_BAR_MATRIX`, `GROUPED_BAR_MATRIX`) share one generator function `barMatrixToTestCase`. The third channel key is `'color'` for bar/stacked and `'group'` for grouped. - -### Bar Chart matrix (19 tests) - -#### N × Q — 6 tests (classic vertical) - -| # | xCard | color | n | what it tests | -|---|-------|-------|---|---------------| -| 1 | 5 | — | 5 | Basic 5 bars | -| 2 | 20 | — | 20 | Label rotation | -| 3 | 30 | — | 30 | Thin bar handling | -| 4 | 100 | — | 100 | Discrete cutoff | -| 5 | 5 | N(3) | 15 | 5 cats × 3 colors | -| 6 | 5 | N(20) | 100 | Color saturation | - -#### Q × N — 3 tests (horizontal) - -| # | yCard | color | n | what it tests | -|---|-------|-------|---|---------------| -| 7 | 10 | — | 10 | Horizontal 10 bars | -| 8 | 100 | — | 100 | Horizontal cutoff | -| 9 | 10 | N(3) | 30 | Horizontal + 3 colors | - -#### T × Q — 3 tests (temporal) - -| # | color | n | what it tests | -|---|-------|---|---------------| -| 10 | — | 24 | Temporal bars | -| 11 | — | 100 | 100 dates — dynamic sizing | -| 12 | N(3) | 72 | Temporal + 3 colors | - -#### Q × T — 2 tests (horizontal temporal) - -| # | color | n | what it tests | -|---|-------|---|---------------| -| 13 | — | 18 | Horizontal temporal | -| 14 | N(3) | 54 | Horizontal temporal + color | - -#### Q × Q — 2 tests (continuous banded) - -| # | n | what it tests | -|---|---|---------------| -| 15 | 20 | Both quant — dynamic resizing | -| 16 | 30 | Equally spaced 1..30 | - -#### Edge combos — 3 tests - -| # | x | y | n | what it tests | -|---|---|---|---|---------------| -| 17 | N | N | grid | Cat × cat (degenerate) | -| 18 | T | T | 20 | Date × date (degenerate) | -| 19 | T | N | 25 | Temporal × categorical | - -### Stacked Bar Chart matrix (12 tests) - -| # | x | y | color | n | what it tests | -|---|---|---|-------|---|---------------| -| 1 | N | Q | N(3) | 12 | Basic stack 4×3 | -| 2 | N | Q | N(5) | 75 | Large 15×5 | -| 3 | N | Q | N(3) | 240 | Very large 80×3 (cutoff) | -| 4 | N | Q | Q(4) | 24 | Numeric color (1–4) | -| 5 | N | Q | Q(30) | 150 | Numeric color (1–30) | -| 6 | T | Q | N(3) | 30 | Temporal stack | -| 7 | T | Q | N(4) | 80 | 20 dates × 4 | -| 8 | Q | Q | N(3) | 30 | Both quant stacked | -| 9 | Q | N | N(3) | 24 | Horizontal stack | -| 10 | Q | T | N(3) | 45 | Horizontal temporal stack | -| 11 | N | N | N(3) | grid | Cat×cat stacked (edge) | -| 12 | T | T | N(3) | 30 | Date×date stacked (edge) | - -### Grouped Bar Chart matrix (12 tests) - -| # | x | y | group | n | what it tests | -|---|---|---|-------|---|---------------| -| 1 | N | Q | N(3) | 12 | Basic grouped 4×3 | -| 2 | N | Q | — | 8 | No group — fallback | -| 3 | N | Q | N(3) | 270 | Very large 90×3 (cutoff) | -| 4 | N | Q | Q(5) | 30 | Numeric group (1–5) | -| 5 | T | Q | N(3) | 36 | Temporal grouped | -| 6 | Q | Q | N(4) | 20 | Both quant + group | -| 7 | Q | N | N(4) | 24 | Horizontal grouped | -| 8 | Q | T | N(3) | 30 | Horizontal temporal grouped | -| 9 | N | Q | Q(50) | 400 | Numeric group (1–50) | -| 10 | N | Q | Q | 50 | Continuous float on group | -| 11 | N | N | N(3) | grid | Cat×cat grouped (edge) | -| 12 | T | T | N(3) | 30 | Date×date grouped (edge) | - -### Coverage summary - -All three bar variants cover common xy-type combinations.

Loaded via dynamic `import()` inside `buildRenderFunction` to avoid bundling issues with CommonJS consumers. -- **Solid.js dependency**: GoFish renders to DOM via Solid.js — it does not produce a serializable spec. The `_gofish` descriptor is for debugging only. -- **`scaffold()` bare vs configured**: `scaffold()` with no arguments returns a bare function whose `.name` is `Function.name` (a string, not callable). Always pass options: `scaffold({h: field}).name("label")`. -- **`circle({fill})` limitation**: GoFish's `circle` mark only accepts literal CSS color strings for `fill`, not data field names. For data-driven scatter color, the template uses `rect({w:8, h:8, fill: field})` as small colored squares instead. -- **No faceting support**: GoFish has no faceting mechanism. Column/row channels are accepted in template definitions but not implemented. -- **Multi-series line/area**: Uses `scaffold({h, fill}).name("pts")` + `group(colorField)` + `line()`/`area()`. The assembler tries `mark.name(label)` first, falls back to `spec.as(label)`. -- **Pie chart**: Uses `chart(data, { coord: clock() })` + `stack(catField, { dir: "x" })` + `rect({ w: valField, fill: catField })`. The `transform: { x: w/2, y: h/2 }` render option centers the chart. -- **Scatter Pie**: Unique to GoFish — scatter-positioned mini pies. The template restructures flat data into `{_key, _x, _y, collection: [...]}` and the mark is a function returning a sub-chart. -- **`--legacy-peer-deps`**: Required when installing `gofish-graphics` due to Solid.js peer dependency conflicts. diff --git a/src/lib/agents-chart/gofish/assemble.ts b/src/lib/agents-chart/gofish/assemble.ts deleted file mode 100644 index 8cc24c08..00000000 --- a/src/lib/agents-chart/gofish/assemble.ts +++ /dev/null @@ -1,529 +0,0 @@ -// Copyright (c) Microsoft Corporation. -// Licensed under the MIT License. - -/** - * GoFish chart assembly — Two-Stage Pipeline Coordinator. - * - * Reuses the **same core analysis pipeline** as all other backends: - * Phase 0: resolveChannelSemantics → ChannelSemantics - * Step 0a: declareLayoutMode → LayoutDeclaration - * Step 0b: convertTemporalData → converted data - * Step 0c: filterOverflow → filtered data, nominalCounts - * Phase 1: computeLayout → LayoutResult - * - * Then diverges for Phase 2 (GoFish-specific): - * template.instantiate → builds GoFish descriptor (_gofish) - * assembler wraps into GoFishSpec with render(container) method - * - * ── Backend Translation Responsibilities ──────────────────────────── - * GoFish renders directly to DOM via Solid.js.
