documd visuals
Routing for every diagram, chart, card and layout this document pipeline can render.
Figures are text, in place. A fence (plantuml · vega · echarts · infographic) or bare HTML
written into the Markdown is the figure: the viewer draws it live, the block stays editable, and nothing
is pre-rendered, built or exported first. documd is optional — export and verification only.
Iron rules
- Allowed fences —
plantuml/puml·vega·vega-lite·echarts·infographic, plus bare HTML — which is how system architecture diagrams, cards and page layouts are drawn. - Nothing outside that list. A fence the list does not name is a bug, not a lesser option — there is no second-tier engine.
- One diagram per fence. Do not put two engines in one block, and never nest fences.
- **HTML is bare, never
```html** — a fenced block becomes an image. Start from a real file rather than inventing one:layered-with-wings.mdfor a system,executive-brief-summary.mdfor a card. - Inline the data.
vega/vega-lite/echartsmust carry their ownvalues/seriesdata; external URLs are unreliable on the export path. - State the reading in the copy. Every figure answers one question — put it in the prose or the
block's
title. - Pick a theme, then colour from it. Colours come from one of the themes indexed in
styles/palette.md; copy that theme's block for your engine and take every value from it — a hex picked by hand, or two themes in one figure, is a bug. Charts pass the categorical ramp in order; cards use one accent plus neutrals.
Route by goal
Find the reader's goal, open the goal guide, pick an example. Engines are suggestions; the guide and examples are authoritative.

Engine cheat sheet
| Engine | Reach for it when | Look elsewhere when |
|---|---|---|
plantuml |
UML/ArchiMate/BPMN semantics, brand and device icons (9,514 stencils), or a relationship graph that should lay itself out | It is a chart |
vega / vega-lite |
The data needs work first — join, window, fold, regression, density, facets, small multiples | One polished chart with heavy styling (echarts) |
echarts |
Report-grade chart or KPI dashboard: axes, series, thresholds, annotations, gauges | The data must be transformed first |
infographic |
A designed-looking board: roadmap, timeline, checklist, comparison, quadrant, knowledge map | Axes, several series or statistical shapes (echarts) |
| HTML/CSS | Cards, memos, overviews, page-level layouts | Another engine already renders that diagram |

Capability boundaries
These are not possible; pick the fallback instead of retrying.
| Want | Fallback |
|---|---|
3D / globe / WebGL charts (no echarts-gl) |
2D echarts; scatter/graph for shape |
| Geographic maps (no bundled map data, no GeoJSON offline) | schematic rectangle layout, or an HTML/CSS region diagram |
dataset.transform in ECharts (throws RangeError in 6.1.0) |
sort and derive upstream, then dataset.source |
Functions in an echarts option (parsed as JSON) |
template strings ("{c}%"), per-item label objects |
External data or images (data.url, remote URLs) |
inline values, data URLs |
| PlantUML WBS / Salt / Timing / ditaa / JSON / YAML / EBNF / nwdiag / SDL / math (parse, draw nothing useful) | @startmindmap, a boxed rectangle tree, HTML/CSS mockups, or a code fence |
| Interactive charts (tooltip, zoom, brush) | annotate directly: labels, thresholds, callouts |
Icons in vega / echarts |
plantuml stencils |
Free-form positioning in infographic |
HTML/CSS for pixel control |
Reading a document
To read a document in the browser or in VS Code, install docu.md Markdown Viewer: https://docu.md.
Exporting & verifying — optional
Authoring never needs this. The documd CLI converts a document or a diagram source to a file,
extracts figures as images, and verifies that blocks render — for when the output is a file. Nothing to
install: npx @markdown-viewer/documd in.md out.docx. Flags, formats and the npm-scope warning:
converting.md.
When a block does not render
- Fence in the allowed list? Exactly one block per figure?
- Is it a listed anti-pattern in that engine's reference (see Engine cheat sheet) — or strict
syntax (JSON for
echarts/vega, no empty lines in bare HTML)? - Then switch to the alternative engine the goal guide names; most scenarios have two.
- Or verify by rendering:
npx @markdown-viewer/documd file.md --assets /tmp/figs.
Where everything lives
catalog/scenarios.md indexes every scenario with its domain, engines, tier and
example path — start there; then goals/<domain>.md, engines/<engine>.md, examples/<domain>/<file>.md.
