### Basic Chart

```tsx
"use client";

import { EvilRadialChart, RadialBar, Tooltip, Legend } from "@/components/evilcharts/charts/radial-chart";
import { type ChartConfig } from "@/components/evilcharts/ui/chart";

const data = [
  { browser: "chrome", visitors: 275 },
  { browser: "safari", visitors: 200 },
  { browser: "firefox", visitors: 187 },
  { browser: "edge", visitors: 173 },
  { browser: "other", visitors: 90 },
];

const chartConfig = {
  chrome: {
    label: "Chrome",
    colors: {
      light: ["#3b82f6"],
      dark: ["#60a5fa"],
    },
  },
  safari: {
    label: "Safari",
    colors: {
      light: ["#10b981"],
      dark: ["#34d399"],
    },
  },
  firefox: {
    label: "Firefox",
    colors: {
      light: ["#f59e0b"],
      dark: ["#fbbf24"],
    },
  },
  edge: {
    label: "Edge",
    colors: {
      light: ["#8b5cf6"],
      dark: ["#a78bfa"],
    },
  },
  other: {
    label: "Other",
    colors: {
      light: ["#6b7280"],
      dark: ["#9ca3af"],
    },
  },
} satisfies ChartConfig;

export function EvilExampleRadialChart() {
  return (
    <EvilRadialChart
      className="h-full w-full p-4"
      data={data}
      nameKey="browser"
      config={chartConfig}
      variant="full" // [!code highlight]
    >
      <Legend isClickable />
      <Tooltip />
      <RadialBar dataKey="visitors" isClickable />
    </EvilRadialChart>
  );
}

```

## Installation


  
  
    ### npm

The radial chart is composible. `<EvilRadialChart>` is the container, and you compose only the parts you need — `<Legend>`, `<Tooltip>`, and a `<RadialBar>` — as its children. The `<RadialBar>` carries its own `glowingBars` and `isClickable`, so styling and interactivity live with the series itself.

```tsx
import {
  EvilRadialChart,
  RadialBar,
  Tooltip,
  Legend,
} from "@/components/evilcharts/charts/radial-chart";
```

```tsx
const data = [
  { browser: "chrome", visitors: 275 },
  { browser: "safari", visitors: 200 },
  { browser: "firefox", visitors: 187 },
];

const chartConfig = {
  chrome: {
    label: "Chrome",
    colors: { light: ["#3b82f6"], dark: ["#60a5fa"] },
  },
  safari: {
    label: "Safari",
    colors: { light: ["#10b981"], dark: ["#34d399"] },
  },
  firefox: {
    label: "Firefox",
    colors: { light: ["#f59e0b"], dark: ["#fbbf24"] },
  },
} satisfies ChartConfig;
```

```tsx
<EvilRadialChart data={data} nameKey="browser" config={chartConfig} variant="full">
  <Legend isClickable />
  <Tooltip />
  <RadialBar dataKey="visitors" isClickable glowingBars={["chrome"]} />
</EvilRadialChart>
```

### Interactive Selection

Add `isClickable` to `<RadialBar>` (and to `<Legend>`) to make bars selectable. Use the `onSelectionChange` callback on `<EvilRadialChart>` to handle selection events:

```tsx
<EvilRadialChart
  data={data}
  nameKey="browser"
  config={chartConfig}
  onSelectionChange={(selection) => {
    if (selection) {
      console.log("Selected:", selection.dataKey, "Value:", selection.value);
    } else {
      console.log("Deselected");
    }
  }}
>
  <Legend isClickable />
  <Tooltip />
  <RadialBar dataKey="visitors" isClickable />
</EvilRadialChart>
```

### Loading State

### isLoading='true'

```tsx
"use client";

import { EvilRadialChart, RadialBar, Tooltip, Legend } from "@/components/evilcharts/charts/radial-chart";
import { type ChartConfig } from "@/components/evilcharts/ui/chart";

const data = [
  { browser: "chrome", visitors: 275 },
  { browser: "safari", visitors: 200 },
  { browser: "firefox", visitors: 187 },
  { browser: "edge", visitors: 173 },
  { browser: "other", visitors: 90 },
];

const chartConfig = {
  chrome: {
    label: "Chrome",
    colors: {
      light: ["#3b82f6"],
      dark: ["#60a5fa"],
    },
  },
  safari: {
    label: "Safari",
    colors: {
      light: ["#10b981"],
      dark: ["#34d399"],
    },
  },
  firefox: {
    label: "Firefox",
    colors: {
      light: ["#f59e0b"],
      dark: ["#fbbf24"],
    },
  },
  edge: {
    label: "Edge",
    colors: {
      light: ["#8b5cf6"],
      dark: ["#a78bfa"],
    },
  },
  other: {
    label: "Other",
    colors: {
      light: ["#6b7280"],
      dark: ["#9ca3af"],
    },
  },
} satisfies ChartConfig;

export function EvilExampleRadialChart() {
  return (
    <EvilRadialChart
      className="h-full w-full p-4"
      data={data}
      nameKey="browser"
      config={chartConfig}
      isLoading // [!code highlight]
    >
      <Legend />
      <Tooltip />
      <RadialBar dataKey="visitors" />
    </EvilRadialChart>
  );
}

```
>  
  
    The radial chart supports loading state with a placeholder animation. You can pass the `isLoading` prop to the chart to show the loading state while your data is being fetched.
  


## Examples

Below are some examples of the radial chart with different configurations. You can customize the `variant`, `innerRadius`, `outerRadius`, and other properties.

### Semi-Circle Variant

### variant='semi'

```tsx
"use client";

import { EvilRadialChart, RadialBar, Tooltip, Legend } from "@/components/evilcharts/charts/radial-chart";
import { type ChartConfig } from "@/components/evilcharts/ui/chart";

const data = [
  { browser: "chrome", visitors: 275 },
  { browser: "safari", visitors: 200 },
  { browser: "firefox", visitors: 187 },
  { browser: "edge", visitors: 173 },
  { browser: "other", visitors: 90 },
];

const chartConfig = {
  chrome: {
    label: "Chrome",
    colors: {
      light: ["#3b82f6"],
      dark: ["#60a5fa"],
    },
  },
  safari: {
    label: "Safari",
    colors: {
      light: ["#10b981"],
      dark: ["#34d399"],
    },
  },
  firefox: {
    label: "Firefox",
    colors: {
      light: ["#f59e0b"],
      dark: ["#fbbf24"],
    },
  },
  edge: {
    label: "Edge",
    colors: {
      light: ["#8b5cf6"],
      dark: ["#a78bfa"],
    },
  },
  other: {
    label: "Other",
    colors: {
      light: ["#6b7280"],
      dark: ["#9ca3af"],
    },
  },
} satisfies ChartConfig;

export function EvilExampleRadialChart() {
  return (
    <EvilRadialChart
      className="h-full w-full p-4"
      data={data}
      nameKey="browser"
      config={chartConfig}
      variant="semi" // [!code highlight]
    >
      <Legend />
      <Tooltip />
      <RadialBar dataKey="visitors" />
    </EvilRadialChart>
  );
}

```
>  
  
    Set `variant="semi"` to create a half-circle radial chart. This is useful for displaying progress or gauges in a more compact space.

```
>  
  
    Add a subtle glow effect to specific bars using the `glowingBars` prop on `<RadialBar>`. Pass an array of bar names (the values from your `nameKey` field) to specify which bars should glow.
  



## API Reference

The chart is composed of several parts. The props below are grouped by the component they belong to.

<ApiHeading>EvilRadialChart</ApiHeading>

The root container. It owns the data, the shared selection state, the loading skeleton, and the chart-wide arc shape. Everything visual is composed as its children.


  ### `data` (required)

type: `TData[]`

Data used to display the chart. An array of objects where each object represents a radial bar (`TData extends Record<string, unknown>`).
  ### `config` (required)

type: `ChartConfig`

Configuration object that defines the chart's bars. Each key should match a value from your `nameKey` field, with corresponding colors.
  ### `nameKey` (required)

type: `keyof TData & string`

The key from your data objects to use for bar names (typically string values used for labels and the legend).
  ### `children` (required)

type: `ReactNode`

The composed chart parts — `<Legend />`, `<Tooltip />`, and a `<RadialBar />`.
  ### `className`

type: `string`

Additional CSS classes to apply to the chart container.
  ### `variant`

type: `"full" | "semi"` · default: `"full"`

The arc shape of the radial chart. `"full"` displays a full circle (360°), `"semi"` displays a half circle (180°).
  ### `innerRadius`

type: `number | string` · default: `"30%"`

The inner radius of the radial bars. Can be a number (pixels) or percentage string.
  ### `outerRadius`

type: `number | string` · default: `"100%"`

The outer radius of the radial bars. Can be a number (pixels) or percentage string.
  ### `defaultSelectedDataKey`

type: `string | null` · default: `null`

The bar name that should be selected by default.
  ### `onSelectionChange`



void">
    Callback fired when a bar is selected or deselected — by clicking a clickable `<RadialBar />` or `<Legend />` entry. Receives an object with `dataKey` (bar name) and `value` (bar value), or `null` when deselected.
  ### `isLoading`

type: `boolean` · default: `false`

Shows a loading placeholder animation when data is being fetched.
  ### `backgroundVariant`

type: `BackgroundVariant`

Background pattern variant to display behind the chart.
  ### `chartProps`



">
    Additional props forwarded to the underlying Recharts RadialBarChart component. Read the [Recharts RadialBarChart documentation](https://recharts.github.io/en-US/api/RadialBarChart/) for available props.


<ApiHeading>RadialBar</ApiHeading>

The radial bar series. Each data row becomes one bar. It generates its own glow filter definitions, so glow effects never collide with other charts on the page.


  ### `dataKey` (required)

type: `string`

The key from your data objects to use for bar values (typically numeric values that determine bar size).
  ### `cornerRadius`

type: `number` · default: `5`

The border radius for the corners of each bar in pixels.
  ### `barSize`

type: `number` · default: `14`

The thickness of each radial bar in pixels.
  ### `showBackground`

type: `boolean` · default: `true`

Whether to render the background track (the unfilled portion of each bar).
  ### `isClickable`

type: `boolean` · default: `false`

Enables interactive clicking on bars to select/deselect them. Unselected bars dim while a selection is active.
  ### `glowingBars`

type: `string[]` · default: `[]`

Array of bar names (values from your `nameKey` field) that should have a glowing effect applied. Creates a smooth outer glow around the specified bars.
  ### `radialBarProps`



, "dataKey">'>
    Additional props forwarded to the underlying Recharts RadialBar component. Read the [Recharts RadialBar documentation](https://recharts.github.io/en-US/api/RadialBar/) for available props.


<ApiHeading>Tooltip</ApiHeading>

The hover tooltip. Labels each bar by its name. Render it to show a tooltip, omit it for none.


  ### `variant`

type: `"default" | "frosted-glass"` · default: `"default"`

Controls the visual style of the tooltip.
  ### `roundness`

type: `"sm" | "md" | "lg" | "xl"` · default: `"lg"`

Controls the border-radius of the tooltip.
  ### `defaultIndex`

type: `number`

When set, the tooltip will be visible by default at the specified data point index.


<ApiHeading>Legend</ApiHeading>

The bar legend. When `isClickable` is set, each entry toggles selection of its bar. Render it to show a legend, omit it for none.


  ### `variant`

type: `"square" | "circle" | "circle-outline" | "rounded-square" | "rounded-square-outline" | …`

The visual style variant for the legend indicators.
  ### `align`

type: `"left" | "center" | "right"` · default: `"center"`

Horizontal placement of the legend.
  ### `verticalAlign`

type: `"top" | "middle" | "bottom"` · default: `"bottom"`

Vertical placement of the legend.
  ### `isClickable`

type: `boolean` · default: `false`

When enabled, each legend entry toggles selection of its bar, driving the shared selection state read by `<RadialBar />`.
