# Visual types

LeapView visuals are defined in dashboard YAML. Every visual has a required `type`, a query, and type-specific presentation settings. Choose the visual that best fits the analytical task; rendering is inferred from its type.

Every preview is compiled and queried from the YAML printed beside it against a fixed documentation dataset. Invalid or stale examples fail documentation generation.

## ECharts interaction capabilities

All built-in charts below use the typed ECharts adapter. “Selectable” means a rendered source row can originate the existing semantic `point_selection` interaction when the YAML declares stable mappings and explicit targets. It does not mean selection is enabled by default.

| Visuals | Source-row selection | Notes |
| --- | --- | --- |
| Line, area, bar, column, scatter, combo | Yes | Each rendered Cartesian datum resolves to its original frame row. |
| Waterfall | Yes | The visible value bar is selectable; the synthetic offset series is silent. |
| Histogram, heatmap, candlestick, boxplot | Yes | Selection requires a stable compiled identity in the shaped source row. |
| Pie, donut, funnel | Yes | Each sector or stage resolves to a source row. |
| Gauge | Yes | The single gauge datum may resolve to its source row. |
| Treemap, sunburst, tree | Yes | A real hierarchy row is selectable when every compiled mapping has a value at that depth; incomplete ancestors and synthetic roots are silent. |
| Graph, Sankey | Yes | Source links are selectable through their private row locators; aggregate renderer nodes remain silent. |
| Radar | No | A radar polygon represents several source rows, so `point_selection` fails compilation. |

Unsupported interaction declarations fail deployment compilation instead of rendering an approximation. Map point and region selection use the separate MapLibre interaction path documented on the [map page](/docs/visuals/map).
