Echarts中太阳图（Sunburst）的实例

目前在项目中要实现一个Echars中的太阳图，但是Echars中的太阳图的数据格式是一个树形结构，如下代码格式如下：

var mapData = [
  {
    name: '会员属性',
    itemStyle: {
      color: '#777'
    },
    children: [
      {
        name: '会员等级',
        itemStyle: {
          color: '#5191d4'
        },
        children: [
          {
            itemStyle: {
