## Overview

Circular layout arranges nodes evenly or at intervals on a circle, and also supports spiral layouts by configuring different startRadius and endRadius. See more circular layout [examples](en/examples#layout-circular) or [source code](https://github.com/antvis/layout/blob/v5/packages/layout/src/circular.ts).

## Usage Scenarios

**Circular layout**:

- Suitable for networks with equal relationships and no hierarchical structure

**Spiral layout**:

- Suitable for implicit hierarchies or time series graphs (such as organizational charts, propagation networks)

## Basic Usage

Other settings use the default configuration (layout width and height default to the entire canvas container)

```js
const graph = new Graph({
  // other configurations
  layout: {
    type: 'circular',
  },
});
```

### ordering

Node ordering on the ring

- `topology`: topological order
- `topology-directed`: topological order (directed graph)
- `degree`: order by degree

If not set (`null`), the order in the array is used directly

### radius

If radius, startRadius, and endRadius are not set, the default is `Math.min(layout width, layout height) / 2`, i.e., fills the entire layout area

## Code Examples

### Basic Circular Layout

```javascript
const graph = new Graph({
  // other configurations
  layout: {
    type: 'circular',
  },
});
```



```ts

import { Graph } from '@antv/g6';

fetch('https://assets.antv.antgroup.com/g6/circular.json')
  .then((res) => res.json())
  .then((data) => {
    const graph = new Graph({
      container: 'container',
      autoFit: 'view',
      data,
      node: {
        style: {
          labelText: (d) => d.id,
          labelFill: '#fff',
          labelPlacement: 'center',
        },
      },
      layout: {
        type: 'circular',
      },
      behaviors: ['drag-canvas', 'drag-element'],
    });

    graph.render();
  });
```


### Spiral Layout

```javascript
const graph = new Graph({
  // other configurations
  layout: {
    type: 'circular',
    startRadius: 10,
    endRadius: 300,
  },
});
```



```ts

import { Graph } from '@antv/g6';

fetch('https://assets.antv.antgroup.com/g6/circular.json')
  .then((res) => res.json())
  .then((data) => {
    const graph = new Graph({
      container: 'container',
      autoFit: 'center',
      data,
      node: {
        style: {
          labelText: (d) => d.id,
          labelFill: '#fff',
          labelPlacement: 'center',
        },
      },
      layout: {
        type: 'circular',
        startRadius: 10,
        endRadius: 300,
      },
      behaviors: ['drag-canvas', 'drag-element'],
    });

    graph.render();
  });
```
