About
Reach for it to rank a handful of categories in a square card: five browsers fit in 250 pixels where a bar chart needs a wide row. Arc length is harder to compare than bar length, so keep to a few rings and use a horizontal bar chart when the gaps matter. For shares of one whole, a pie or donut says so plainly.
Each browser gets a ring, Chrome innermost and Other outermost. Every ring starts at three o'clock and runs counterclockwise as far as its count, over a muted track that marks the full circle.

FAQ
What's the gray ring behind each bar?
A track: an extra radialBarAngle in its own polar() layer under the colored one, drawing every browser to maxVisitors, the angle scale's maximum, in var(--muted). The tracks read the pointer; the colored rings are decorative(). For bare rings, as the Radial Chart with Grid has, remove the track layer and unwrap the rings from decorative().
What value closes the circle?
The largest value. The angle scale's domain is [0, maxVisitors], so Chrome's 275 makes a full turn, as in Recharts. Set the domain to a target, or to [0, 100] for percentages, and draw the tracks' angle2 at the same value.
Which ring is which?
Rows go from the inside out in data order: Chrome is the innermost ring, Other the outermost. Sort chartData to change the order. Outer rings are longer for the same value, so putting the largest outside exaggerates it; inside keeps it honest.
How do I color the rings?
Each ring is painted with its browser's variable, var(--color-chrome) to var(--color-other), and chartConfig maps those keys to --chart-1 through --chart-5. Change one config color to recolor that browser. The visitors entry has no color: it only labels the value.
Why does the tooltip show the browser and no title?
There's no category axis to title the tooltip, so it hides its label and names the row by its browser: ChartContainer's tooltip prop passes hideLabel and nameKey: "browser" to ChartTooltipContent, and valueKey: "visitors" reads the count, since a point in polar() carries an angle, not a value.
API Reference

- Type
(ChartTooltipContentOptions & { class?: string }) | false
renderTooltip?Snippet<[ChartTooltipBodySnippetContext]>
A whole tooltip body of your own, in place of ChartTooltipContent: it gets the focused points (each with its datum, group and color). A snippet.

Snippet<[ChartTooltipBodySnippetContext]>
defaultIndex?number
The category whose tooltip shows before any pointer, as Recharts' defaultIndex.
height?number
A fixed height in pixels for the chart, in place of the container's.
aspectRatio?number
A width-to-height ratio for the chart, in place of the container's height.
initialWidth?number
The width the chart renders at before it's measured.
onFocusChange?(point: ChartPoint | null) => void
Called as the focused point changes: a pointer, a key or a tap.
- Type
(point: ChartPoint | null) => void
onFocusGroupChange?(points: readonly ChartPoint[]) => void
Called with every point at the focused category (a stacked or grouped chart's).
- Type
(points: readonly ChartPoint[]) => void
onSelect?(point: ChartPoint | null) => void
Called when a point is clicked or picked with Enter.
- Type
(point: ChartPoint | null) => void
--color-<key>?color
Each config key's color (its theme color in light and dark), set on the container: the marks paint with var(--color-<key>).
ChartTooltipContent
<div>
pointsreadonly ChartPoint[]
The focused points, from the tooltip's context. ChartContainer passes them to its default body; a body of your own passes its context's.
indicator?"dot" | "line" | "dashed"
The indicator's shape beside each row.

false
hideIndicator?boolean
Hides each row's color indicator.
- Default
false
label?string
The label's text in place of the focused category, looked up in config.
labelKey?string
The datum field (or config key) the label is read from, looked up in config.
nameKey?string
The datum field (or config key) each row's series is read from: a pie's browser.
valueKey?string
The datum field each row's value is read from, for points that carry geometry rather than values (a pie's, from pie()).
color?string
One indicator color for every row, in place of each series' own.
labelFormatter?(label: string, points: readonly ChartPoint[]) => string
Formats the label (the config's label or the category), with the rows' points: a date written out, a unit.

formatter?Snippet<[{ index, item, name, value }]>

Snippet<[{ index, item, name, value }]>
class?string
Classes for the tooltip's card.
ChartLegend
<div>

color?string
Its color in both themes: a token (var(--chart-1)) or any CSS color.
theme?{ light: string; dark: string }
A color for each theme, in place of color.
Helpers
chartTooltip?(settings?: ChartTooltipSettings) => ChartDefinitionOptions
defineChart's second argument for a chart with a tooltip: what a pointer or a key focuses (group-x, each category's series, by default), the focus ring, and the host ChartContainer draws its body in.
- Type
(settings?: ChartTooltipSettings) => ChartDefinitionOptions
chartTheme?ChartTheme
defineChart's theme in the site's tokens: the text, the grid and the palette (--chart-1 to --chart-5).
chartColors?(config: ChartConfig, keys?: readonly string[]) => { domain: string[]; range: string[] }
defineChart's color: each series key (in config order, or keys') painted var(--color-<key>), for marks with a color channel.
- Type
(config: ChartConfig, keys?: readonly string[]) => { domain: string[]; range: string[] }
chartLinearScale?() => LinearScale
A value axis drawn as Recharts draws its default one: zero in the domain, five nice ticks. Pass it as a factory: y: { scale: chartLinearScale }.
- Type
() => LinearScale
curveNatural?CurveFactory
D3's natural curve, for a smooth line or area: curve: d3Curve(curveNatural).
curveStep?CurveFactory
D3's step curve, for a line or area that holds each value: curve: d3Curve(curveStep).
curveMonotoneX?CurveFactory
D3's monotone curve, smooth without overshooting a point: curve: d3Curve(curveMonotoneX).
