我正在开发VueJS和Vue Echarts库，用于创建数据可视化。

以下是Vue Echarts的Polar chart演示：

官方网站：https://ecomfe.github.io/vue-echarts/demo/ GitHub页面：https://github.com/ecomfe/vue-echarts

<template>
<v-chart :options="polar"/>
</template>

<style>
/**
 * The default size is 600px×400px, for responsive charts
 * you may need to set percentage values as follows (also
 * don't forget to provide a size for the container).
 */
.echarts {
  width: 100%;
  height: 100%;
}
</style>

<script>
import ECharts from 'vue-echarts'
import 'echarts/lib/chart/line'
import 'echarts/lib/component/polar'

export default {
  components: {
    'v-chart': ECharts
  },
  data () {
    let data = []

    for (let i = 0; i <= 360; i++) {
        let t = i / 180 * Math.PI
        let r = Math.sin(2 * t) * Math.cos(2 * t)
        data.push([r, i])
    }

    return {
      polar: {
        title: {
          text: '极坐标双数值轴'
        },
        legend: {
          data: ['line']
        },
        polar: {
          center: ['50%', '54%']
        },
        tooltip: {
          trigger: 'axis',
          axisPointer: {
            type: 'cross'
          }
        },
        angleAxis: {
          type: 'value',
          startAngle: 0
        },
        radiusAxis: {
          min: 0
        },
        series: [
          {
            coordinateSystem: 'polar',
            name: 'line',
            type: 'line',
            showSymbol: false,
            data: data
          }
        ],
        animationDuration: 2000
      }
    }
  }
}
</script>

结果：Polar Chart Looks Like

我想创建饼图，而不是极点。我查看了几个网站，但没有找到我的结果。

我需要的是：this pie chart
