### Basic Chart

```tsx
"use client";

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

const data = [
  { skill: "JavaScript", desktop: 186, mobile: 80 },
  { skill: "TypeScript", desktop: 305, mobile: 200 },
  { skill: "React", desktop: 237, mobile: 120 },
  { skill: "Node.js", desktop: 173, mobile: 190 },
  { skill: "CSS", desktop: 209, mobile: 130 },
  { skill: "Python", desktop: 214, mobile: 140 },
];

const chartConfig = {
  desktop: {
    label: "Desktop",
    colors: {
      light: ["#3b82f6"],
      dark: ["#60a5fa"],
    },
  },
  mobile: {
    label: "Mobile",
    colors: {
      light: ["#10b981"],
      dark: ["#34d399"],
    },
  },
} satisfies ChartConfig;

export function EvilExampleRadarChart() {
  return (
    <EvilRadarChart
      isClickable
      className="h-full w-full p-4"
      data={data}
      dataKey="skill"
      dotVariant="colored-border"
      activeDotVariant="default"
      chartConfig={chartConfig}
      variant="filled" // [!code highlight]
    />
  );
}

```

## Installation


  
  
    ### npm

```bash
npx shadcn@latest add @evilcharts/radar-chart
```

### yarn

```bash
yarn shadcn@latest add @evilcharts/radar-chart
```

### bun

```bash
bunx --bun shadcn@latest add @evilcharts/radar-chart
```

### pnpm

```bash
pnpm dlx shadcn@latest add @evilcharts/radar-chart
```
  
  
    
      
        ### Install the following dependencies:
        
          ### npm

```bash
npm install recharts
```

### yarn

```bash
yarn add recharts
```

### bun

```bash
bun add recharts
```

### pnpm

```bash
pnpm add recharts
```
        
      
      
        ### Copy and paste the following code snippets into your project.
         
          To use the chart, first create the folder `evilcharts` and a subfolder called `charts` inside your `components` directory.
          Then, copy the following base radar-chart code into a new file in that folder.

        ### Now, Let's add the chart component to your project.
        
          These Components are required by the chart component to render the chart. Make a folder called `ui` inside the `evilcharts` folder and paste the code there.

          Below is main chart component.

## Usage

```tsx
import { EvilRadarChart } from "@/components/evilcharts/charts/radar-chart";
```

```tsx
const data = [
  { skill: "JavaScript", desktop: 186, mobile: 80 },
  { skill: "TypeScript", desktop: 305, mobile: 200 },
  { skill: "React", desktop: 237, mobile: 120 },
  { skill: "Node.js", desktop: 173, mobile: 190 },
  { skill: "CSS", desktop: 209, mobile: 130 },
];

const chartConfig = {
  desktop: {
    label: "Desktop",
    colors: { light: ["#3b82f6"], dark: ["#60a5fa"] },
  },
  mobile: {
    label: "Mobile",
    colors: { light: ["#10b981"], dark: ["#34d399"] },
  },
} satisfies ChartConfig;

<EvilRadarChart  
  data={data}
  dataKey="skill"
  chartConfig={chartConfig}
/>
```

### Interactive Selection

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

```tsx
<EvilRadarChart
  data={data}
  dataKey="skill"
  chartConfig={chartConfig}
  isClickable={true}
  onSelectionChange={(selectedDataKey) => {
    if (selectedDataKey) {
      console.log("Selected:", selectedDataKey);
    } else {
      console.log("Deselected");
    }
  }}
/>
```

### Loading State

### isLoading='true'

```tsx
"use client";

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

const data = [
  { skill: "JavaScript", desktop: 186, mobile: 80 },
  { skill: "TypeScript", desktop: 305, mobile: 200 },
  { skill: "React", desktop: 237, mobile: 120 },
  { skill: "Node.js", desktop: 173, mobile: 190 },
  { skill: "CSS", desktop: 209, mobile: 130 },
  { skill: "Python", desktop: 214, mobile: 140 },
];

const chartConfig = {
  desktop: {
    label: "Desktop",
    colors: {
      light: ["#3b82f6"],
      dark: ["#60a5fa"],
    },
  },
  mobile: {
    label: "Mobile",
    colors: {
      light: ["#10b981"],
      dark: ["#34d399"],
    },
  },
} satisfies ChartConfig;

export function EvilExampleRadarChart() {
  return (
    <EvilRadarChart
      className="h-full w-full p-4"
      data={data}
      dataKey="skill"
      hideDots
      chartConfig={chartConfig}
      isLoading // [!code highlight]
    />
  );
}

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


## Examples

Below are some examples of the radar chart with different configurations.

### Lines Variant

### variant='lines'

```tsx
"use client";

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

const data = [
  { skill: "JavaScript", desktop: 186, mobile: 80 },
  { skill: "TypeScript", desktop: 305, mobile: 200 },
  { skill: "React", desktop: 237, mobile: 120 },
  { skill: "Node.js", desktop: 173, mobile: 190 },
  { skill: "CSS", desktop: 209, mobile: 130 },
  { skill: "Python", desktop: 214, mobile: 140 },
];

const chartConfig = {
  desktop: {
    label: "Desktop",
    colors: {
      light: ["#3b82f6"],
      dark: ["#60a5fa"],
    },
  },
  mobile: {
    label: "Mobile",
    colors: {
      light: ["#10b981"],
      dark: ["#34d399"],
    },
  },
} satisfies ChartConfig;

export function EvilExampleRadarChart() {
  return (
    <EvilRadarChart
      className="h-full w-full p-4"
      data={data}
      dataKey="skill"
      dotVariant="colored-border"
      activeDotVariant="default"
      chartConfig={chartConfig}
      variant="lines" // [!code highlight]
    />
  );
}

```
>  
  
    Set `variant="lines"` to show only the outline without fill. This is useful for comparing multiple datasets more clearly.
  


### Circle Grid

### gridType='circle'

```tsx
"use client";

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

const data = [
  { skill: "JavaScript", desktop: 186, mobile: 80 },
  { skill: "TypeScript", desktop: 305, mobile: 200 },
  { skill: "React", desktop: 237, mobile: 120 },
  { skill: "Node.js", desktop: 173, mobile: 190 },
  { skill: "CSS", desktop: 209, mobile: 130 },
  { skill: "Python", desktop: 214, mobile: 140 },
];

const chartConfig = {
  desktop: {
    label: "Desktop",
    colors: {
      light: ["#3b82f6"],
      dark: ["#60a5fa"],
    },
  },

      dark: ["#34d399"],
    },
  },
} satisfies ChartConfig;

export function EvilExampleRadarChart() {
  return (
    <EvilRadarChart
      className="h-full w-full p-4"
      data={data}
      dataKey="skill"
      dotVariant="colored-border"
      activeDotVariant="default"
      chartConfig={chartConfig}
      gridType="circle" // [!code highlight]
    />
  );
}

```
>  
  
    Set `gridType="circle"` to use circular grid lines instead of the default polygon grid.
