# Radial chart

A React component in [Beamline](https://beamline.io/)'s [Charts & data-vis](https://beamline.io/components/charts) category. Live demo: https://beamline.io/components/radial-chart

Progress of a few measures toward their targets as concentric rings, full or half circle, with a centre readout and a list of each ring's value, target and percent.

## Use it for

- A handful of goals side by side (quarterly targets, quota attainment).
- A compact progress visual in a card.

## Not for

- Precise comparisons ([bar-list](https://beamline.io/components/bar-list) or [bar-chart](https://beamline.io/components/bar-chart)).
- One value against a range with bands ([gauge](https://beamline.io/components/gauge)).

## Anatomy

- title
- rings with tracks
- centre readout
- ring list (swatch, name, value of target, percent)
- table button

## Variants

- **0**: shape: full · semi
- **1**: target per row or one shared max

## States

- loading (skeleton)
- empty (no data)
- missing values (listed as Not measured, never drawn as 0)
- active (hover or focus previews)
- selected (click or Enter pins)
- table view
- over target (ring full, percent above 100)

## Keyboard

- Tab moves through the ring list; focus previews the ring and the centre reads it
- Enter or Space pins it; Escape clears

## Motion

Rings sweep to their value once (600 ms); the active ring brightens and others dim; the centre number rolls. Nothing moves under reduced motion.

## Props

| Prop | Type | Default | Description |
| --- | --- | --- | --- |
| `data / label / value` | `T[] / keyof T / keyof T` | — |  |
| `target` | `keyof T \| number` | — | A column with each row's target, or one shared maximum (default: the largest value). |
| `title / hideTitle / description` | `string / boolean / ReactNode` | — | The figure's name is always its accessible name. |
| `format` | `(v: number) => string` | — |  |
| `table` | `boolean` | — | Offer the table view (default on). |
| `loading` | `boolean` | — |  |
| `actions` | `ReactNode` | — |  |
| `className` | `string` | — |  |
| `shape` | `"full" \| "semi"` | — |  |
| `colors` | `string[]` | — |  |
| `size` | `number` | — |  |
| `list` | `boolean` | — |  |
| `active / defaultActive / onActiveChange` | `string \| null` | — | The selected item; hover and focus preview others. |
| `classNames` | `ChartClassNames` | — | Frame, tooltip and slice-list parts as applicable to this chart. |
| `style / ref` | `CSSProperties / Ref<HTMLElement>` | — | The native chart figure; layout measurement refs stay internal. |
