+- [charts] Provide `dataIndex` in `LinePlot` and `AreaPlot` onItemClick (#23144) @JCQuintas
+
+  `LinePlot` and `AreaPlot` `onItemClick` (and `LineChart`'s `onLineClick`/`onAreaClick`) now provide the `dataIndex` of the closest data point to the click.
+
+  The identifier passed to `LinePlot`, `AreaPlot`, and `MarkPlot` `onItemClick` is now typed as the new `LineItemClickIdentifier`, where `dataIndex` is required. The callback is no longer fired in the pathological case where no data point can be resolved from the click position.

- [charts] Provide `dataIndex` in `LinePlot` and `AreaPlot` `onItemClick` (#23144) @JCQuintas

maybe we should move that explanatory section to the highlights? WDYT @JCQuintas?
