Studio and the AI builder recognize a closed vocabulary of chart types. Your `// viz:` metadata line must name one of these, and the type drives which Configure knobs appear and how the checks read your component.

## Recognized types

- `bar`
- `line`
- `area`
- `scatter`
- `donut`
- `heatmap`
- `table`
- `kpi`
- `map`
- `sankey`
- `waterfall`
- `sunburst`
- `radar`
- `bullet`
- `bump`
- `polar`
- `nightingale`
- `chord`
- `treemap`
- `streamgraph`
- `network`
- `other`

Use `other` only when nothing else fits; it turns off the type-specific checks and knobs.

## FAQ

### Where does the chart type come from?
The `// viz: {"type":"..."}` comment at the top of your component. It must be one of the types above.
