树形图控制树枝粗细

1.背景

收入波动分析，使用脑图（树形图）展示不同维度的权重，权重大的对应的树枝更粗些

2.echarts测试

# 代码
option = {
  series: [{
    type: "tree",
    data: [{
      name: "root",
      children: [{
        name: "Child A",
        lineStyle: {
          width: 5
        },
        children: [{
          name: "Leaf C"
        }, {
          name: "Leaf D"
        }, {
          name: "Leaf E",
          lineStyle: {
            width: 10
          },
        }, {
          name: "Leaf F"
        }]
      }, {
        name: "Child B",
        children: [{
