## Usage

#### Graph with F6

```ts
import F6 from '@antv/f6';

Page({
  data: {
    canvasWidth: 400,
    canvasHeight: 610,
  },

  onLoad() {
    this.ctx = my.createCanvasContext('canvas');
    this.drawF6();
  },

  drawF6() {
    const { canvasWidth, canvasHeight } = this.data;
    const data = {
      nodes: [
        {
          id: 'node1',
          label: 'Circle1',
