### Basic Chart

```tsx
"use client";

import { EvilPieChart } from "@/components/evilcharts/charts/pie-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 EvilExamplePieChart() {
  return (
    <EvilPieChart
      isClickable
      className="h-full w-full p-4"
      data={data}
      dataKey="visitors"
      nameKey="browser"
      chartConfig={chartConfig}
    />
  );
}

```

## Usage

```tsx
import { EvilPieChart } from "@/components/evilcharts/charts/pie-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;
```

### Interactive Selection

When `isClickable` is enabled, you can use the `onSelectionChange` callback to handle selection events:

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

```tsx
<EvilPieChart  
  data={data}
  dataKey="visitors"
  nameKey="browser"
  chartConfig={chartConfig}
/>
```

### Loading State

### isLoading='true'

```tsx
"use client";

import { EvilPieChart } from "@/components/evilcharts/charts/pie-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"],
    },
  },

export function EvilExamplePieChart() {
  return (
    <EvilPieChart
      className="h-full w-full p-4"
      data={data}
      dataKey="visitors"
      nameKey="browser"
      chartConfig={chartConfig}
      isLoading // [!code highlight]

      chartConfig={chartConfig}
    />
  );
}

```

### Donut Chart

### innerRadius={60}

```tsx
"use client";

import { EvilPieChart } from "@/components/evilcharts/charts/pie-chart";
import { type ChartConfig } from "@/components/evilcharts/ui/chart";

const data = [
  { browser: "chrome", visitors: 275 },

    colors: {
      light: ["#3b82f6"],
      dark: ["#60a5fa"],
    },
  },
  safari: {
    label: "Safari",
    colors: {
      light: ["#10b981"],
      dark: ["#34d399"],
    },
  },
  firefox: {
    label: "Firefox",
    colors: {
      light: ["#f59e0b"],
      dark: ["#fbbf24"],

    label: "Edge",
    colors: {
      light: ["#8b5cf6"],
      dark: ["#a78bfa"],
    },
  },
  other: {
    label: "Other",
    colors: {
      light: ["#6b7280"],
      dark: ["#9ca3af"],
    },
  },
} satisfies ChartConfig;

      innerRadius={60} // [!code highlight]
    />
  );
}

```
>  
  
    Set `innerRadius` to a value greater than 0 to create a donut chart. The inner radius creates the hole in the center of the pie.
  


### Padded Sectors

### paddingAngle={4} cornerRadius={8}

```tsx
"use client";

import { EvilPieChart } from "@/components/evilcharts/charts/pie-chart";
import { type ChartConfig } from "@/components/evilcharts/ui/chart";

      cornerRadius={8} // [!code highlight]
    />
  );
}

```
>  
  
    Use `paddingAngle` to add space between sectors and `cornerRadius` to round the corners of each sector. Combine with `innerRadius` for a modern donut look.
  


### innerRadius={60} paddingAngle={-20} cornerRadius={100}

```tsx
"use client";

import { EvilPieChart } from "@/components/evilcharts/charts/pie-chart";
import { type ChartConfig } from "@/components/evilcharts/ui/chart";

  chrome: {
    label: "Chrome",
    colors: {
      light: ["#3b82f6"],
      dark: ["#60a5fa"],
    },
  },

      chartConfig={chartConfig}
      innerRadius={60}
      paddingAngle={-25}
      cornerRadius={99}
    />
  );
}

```
>  
  
    Use a negative `paddingAngle` to create overlapping sectors with a high `cornerRadius` for a petal-like effect. Combine with `innerRadius` for a flower-shaped donut chart.

      showLabels // [!code highlight]
    />
  );
}

```
>
