echarts做了一个气泡图

今天，用echarts做了一个气泡图，功能只是实现了，样式还需要自己修改，
我用的echarts的版本是v4.2.1

<template>
  <div>
    <div style="width:50%">
      <div class="perstatimg">
        <div id="myHorizontal" class="myHorizontalClass" :style="{ width: '643px', height: '300px' }"></div>
      </div>
    </div>
  </div>
</template>
 
<script>
export default {
  data() {
    return {
    }
  },
  mounted(){
    this.drawLine()
  },
  methods: {
    // 画图
    drawLine() {
      // 基于准备好的dom，初始化echarts实例
      let myChart = this.$echarts.init(document.getElementById("myHorizontal"));
      // 绘制流程数量图表
      myChart.setOption({
        backgroundColor: this.$echarts.graphic.RadialGradient(0.3, 0.3, 0.8, [
          {
            offset: 0,
