Circle Packing is a variant of tree structure diagrams that uses circles (instead of rectangles) to represent the entire hierarchy layer by layer. It is commonly used to describe containment relationships between data.

## Getting Started

```js
import { Chart } from '@antv/g2';
import { interpolateHcl } from 'd3-interpolate';

const chart = new Chart({
  container: 'container',
  padding: 20,
});

chart.options({
  type: 'pack',
  data: {
    type: 'fetch',
    value: 'https://assets.antv.antgroup.com/g2/flare.json',
  },
  layout: {
    padding: 5,
  },
  encode: { value: 'value', color: 'depth' },
  scale: {
    color: {
      domain: [0, 5],
      range: ['hsl(152,80%,80%)', 'hsl(228,30%,40%)'],
      interpolate: interpolateHcl,
    },
  },
  style: {
    labelText: (d) => (d.r >= 10 && d.height === 0 ? `${d.data.name}` : ''),
  },
  axis: false,
  legend: false,
});

chart.render();
```

### layout

| Property | Description   | Type                 | Default Value                 |
| -------- | ------------- | -------------------- | ----------------------------- |
| sort     | Sorting mode  | `((a, b) => number)` | `(a, b) => b.value - a.value` |
| padding  | Inner spacing | `number`             | 0                             |

### style

Composite graphic marks need to use different prefixes to distinguish graphic configurations.

- `<label>`: Prefix for data labels, for example: `labelText` sets the text of the label.
