# markvis (full)
Quantitative Markdown charts. Path: fence | GFM | HTML comment → parser → Chart IR → SVG + table fallback.
## Grammar
1. Optional `markvis: 2`
2. CORE headers: `type`, `title`, `theme`, `palette`, `unit`, `x`, `y`, `series`
3. Type-local encodings when legal: `layout`, `innerRadius`, `min`, `max`
4. Blank line
5. CSV or GFM table with a header row
Language tags `chart`, `markvis`, `vis` share one parser.
## Types (CORE)
| type | notes |
| --- | --- |
| bar | keep row order; optional `layout` |
| line | multi-series via `series`; keep row order; optional `layout` |
| area | same order rule as line; optional `layout` |
| scatter | numeric x and y |
| pie | values ≥ 0; do not normalize to 100; optional `innerRadius` |
| hist | continuous x; table keeps raw rows |
| heatmap | x cat × series cat, y intensity; long form; series required |
| funnel | x stage, y ≥ 0; keep order; series ignored |
| waterfall | x step, y signed delta; running baseline; series ignored |
| radar | x spoke, y ≥ 0; optional series; scale max = max(y) or 1 |
| gauge | first row; optional min/max; series ignored |
+ | sankey | x source, series target (required), y flow ≥ 0; one row = one link |
+ | treemap | x label, y ≥ 0; optional series parent; two levels max |
## Encodings
| field | legal on | values | omit |
| --- | --- | --- | --- |
| layout | bar line area | grouped \| stacked \| percent | grouped |
| innerRadius | pie | [0, 1] | theme PIE_INNER_RATIO (explicit 0 = solid) |
| min | gauge | number | 0 |
| max | gauge | number | max(y, 1) |
- Wrong type / bad value → E_UNKNOWN_FIELD + table. Do not invent donut, stacked-bar, sankey, or treemap type ids. Gauge with both min and max set requires min < max.

## Errors (stable codes)
E_UNKNOWN_TYPE, E_TYPE_TYPO, E_JSON_DATA, E_MISSING_HEADER, E_EMPTY_DATA, E_EXTRA_COLUMN, E_DUP_COLUMN, E_UNKNOWN_FIELD, E_PIE_NEGATIVE, E_NEGATIVE_VALUE, E_YAML_TABLE_CONFLICT, E_EMPTY_FENCE, E_UNKNOWN_THEME, E_UNKNOWN_PALETTE.
Optional `theme:` grammar pack: folio|highcharts|shadcn|docs|ant|recharts (default folio).
Optional `palette:` color table: ink|porcelain|warm|cool|vivid (omit → theme default colors). Theme ≠ palette.
Invalid → table + one-line error. Never drop recovered rows.

## Product boundaries
- No chart runtimes in core. No JSON-as-default data. Do not invent donut / sankey / treemap / stacked-bar as type ids (use encodings or the Wave 2 packs). Structure diagrams stay outside this language. Full type catalog grows as packs; see docs/TYPES.md.
