## When to use

- A share of a total split across a few sources, browsers or funds around a donut
- A donut with the total in its center and a legend row per segment under period tabs

## When not to use

- A single figure measured against a target on an arc gauge: use the [Radial Chart blocks](https://reui.io/blocks/chart/radial-chart.md)
- Shares across more than a handful of categories that need exact comparison: use the [Bar Chart blocks](https://reui.io/blocks/chart/bar-chart.md)

## Agent notes

- The donut hole is the `innerRadius` on `Pie`, and slice labels and colors come from `chartConfig`

## Blocks

- [Inflows by Source](https://reui.io/blocks/chart/pie-chart/chart-13.md): Capital inflows donut chart card with Week, Month, Year tabs and a per-source legend. Best for a full donut that adds an Other Sources slice for the untracked share, with a dashed center ring, an info tooltip and a reveal.
- [Browser Usage](https://reui.io/blocks/chart/pie-chart/chart-27.md): Browser usage donut chart card with 5D, 2W and 1M period tabs and total visitors KPI. Best for a donut with in slice visitor counts across 5 browser slices, a summed total, 5D, 2W and 1M tabs, an Export button and a footnote.
