## What it does

Instructs Cursor to build visualisations using Semiotic high-level components such as `LineChart`, `BarChart`, or `SankeyDiagram`. It directs the assistant away from raw Stream Frames because HOCs contain built-in error boundaries and consume plain data objects directly.

The rule documents prop definitions for coordinate and network charts, detailing margins, tooltips, and legends. It also structures the `onObservation` callback to capture hover, click, and brush interactions with native data payloads.

The rules require the `semiotic` npm package in your project and `strict: true` enabled in TypeScript.

## Install

### Cursor (native platform)

**Manually: put the files in place**
- File: `.cursor/rules/semiotic-react-dataviz-cursorrules-prompt-file.mdc` — Frontmatter: description, globs, alwaysApply

### Claude Code

**Manually: put the files in place**
- File: `.claude/rules/semiotic-react-dataviz-cursorrules-prompt-file.md` — The paths frontmatter field limits the files: move globs from the source into paths

### Codex

**AGENTS.md**
- Codex reads AGENTS.md: paste the rule text there

### GitHub Copilot

**Manually: put the files in place**
- File: `.github/instructions/semiotic-react-dataviz-cursorrules-prompt-file.instructions.md` — The applyTo field sets which files it applies to: move globs from the source into applyTo

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/rules/semiotic-react-dataviz-cursorrules-prompt-file.md`

### Cline

**Manually: put the files in place**
- File: `.clinerules/semiotic-react-dataviz-cursorrules-prompt-file.md`

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/PatrickJS/awesome-cursorrules/tree/HEAD/rules/semiotic-react-dataviz-cursorrules-prompt-file.mdc

## When to use it
- scaffold Semiotic React components with correct HOC signatures
- configure interaction listeners via the onObservation callback
- set up complex XY charts like QuadrantChart and ConnectedScatterplot
- connect network diagrams such as SankeyDiagram and ForceDirectedGraph

## Example prompts
- Create a DonutChart component showing market share with centered text
- Build a LineChart with anomaly detection and linear scaling
- Generate a SankeyDiagram visualizing flow data between nodes

# Semiotic — AI Assistant Guide

## Quick Start
- Install: `npm install semiotic`
- Import: `semiotic`, `semiotic/xy`, `semiotic/ordinal`, `semiotic/network`, `semiotic/geo`, `semiotic/realtime`, `semiotic/ai`, `semiotic/data`, `semiotic/server`
- CLI: `npx semiotic-ai [--schema|--compact|--examples|--doctor]`
- MCP: `npx semiotic-mcp`
- Every HOC has a built-in error boundary (never blanks the page) and dev-mode validation warnings

## Architecture
- **HOC Charts**: Simple props, sensible defaults. **Stream Frames**: Full control.
- **Always use HOC charts** (`ForceDirectedGraph`, `SankeyDiagram`, `LineChart`, `RealtimeLineChart`, `ChoroplethMap`, etc.) unless you need sophisticated control they don't expose. Stream Frames (`StreamNetworkFrame`, `StreamXYFrame`, `StreamOrdinalFrame`, `StreamGeoFrame`) are low-level escape hatches — they accept raw `RealtimeNode`/`RealtimeEdge` wrappers in callbacks, not your data objects directly.
- Every HOC accepts `frameProps` to pass through. TypeScript `strict: true`.

## Common Props (all HOCs)
`title`, `width` (600), `height` (400), `responsiveWidth`, `responsiveHeight`, `margin`, `className`, `enableHover` (true), `tooltip` (boolean | `(datum) => ReactNode` | config object), `showLegend`, `showGrid` (false), `frameProps`, `onObservation` (callback, see below), `chartId`, `loading` (false), `emptyContent`, `legendInteraction` ("none"|"highlight"|"isolate"), `legendPosition` ("right"|"left"|"top"|"bottom", default "right"), `emphasis` ("primary"|"secondary")

### tooltip
`tooltip` accepts: `true` (default tooltip), `false` (disabled), a **function** `(datum: Record<string, any>) => ReactNode`, or a config `{ fields?: string[], title?: accessor, format?: fn, style?: CSSProperties }`. The function form receives your raw data object directly.

### onObservation
`onObservation` receives a `ChartObservation` with `type` and event-specific fields:
- **hover**: `{ type: "hover", datum: <your data>, x, y, timestamp, chartType, chartId }`
- **hover-end**: `{ type: "hover-end", timestamp, chartType, chartId }`
- **click**: `{ type: "click", datum: <your data>, x, y, timestamp, chartType, chartId }`
- **brush**: `{ type: "brush", extent: { x: [min, max], y: [min, max] }, timestamp, chartType }`
- **selection**: `{ type: "selection", selection: { name, fields }, timestamp, chartType }`

The `datum` field contains your original data object (not a wrapper).

## XY Charts (`semiotic/xy`)

**LineChart** — `data`, `xAccessor` ("x"), `yAccessor` ("y"), `lineBy`, `lineDataAccessor` ("coordinates"), `colorBy`, `colorScheme`, `curve`, `lineWidth` (2), `showPoints`, `pointRadius` (3), `fillArea`, `areaOpacity` (0.3), `anomaly` (AnomalyConfig), `forecast` (ForecastConfig), `directLabel` (boolean|{position,fontSize}), `gapStrategy` ("break"|"interpolate"|"zero"), `xScaleType` ("linear"|"log"), `yScaleType` ("linear"|"log")

**AreaChart** — LineChart props + `areaBy`, `y0Accessor` (band/ribbon), `gradientFill` (boolean|{topOpacity,bottomOpacity}), `areaOpacity` (0.7), `showLine` (true)

**StackedAreaChart** — flat array data + `areaBy` (required, groups into stacked areas), `colorBy`, `normalize` (false). Do NOT use `lineBy` or `lineDataAccessor` — those are LineChart props.

**Scatterplot** — `data`, `xAccessor`, `yAccessor`, `colorBy`, `sizeBy`, `sizeRange`, `pointRadius` (5), `pointOpacity` (0.8), `marginalGraphics`

**BubbleChart** — Scatterplot + `sizeBy` (required), `sizeRange` ([5,40]), `bubbleOpacity` (0.6)
```
