echarts树图实现数据以树的结构展示，其效果如下：

代码如下：

const data = {
  name: 'XXX公司',
  itemStyle: {
    color: '#00ADD0'
  },
  children: [
    {
      name: '网络主机',
      itemStyle: {
        color: '#FFA12F'
      },
      children: [
        {
          name: '普通路由器',
          itemStyle: {
            color: '#604BFF'
          },
          children: [
            {
              name: '智能网关',
              itemStyle: {
                color: '#95F300'
              }
            },
            {
              name: '192.168.1.0/24'
            }
          ]
        }
      ]
    },
    {
      name: '企业路由器'
    },
    {
      name: '三级交换机'
    }
  ]
};
option = {
  tooltip: {
    trigger: 'item',
    triggerOn: 'mousemove'
  },
  series: [
    {
      type: 'tree',
      data: [data],
      left: '2%',
      right: '2%',
      top: '8%',
      bottom: '20%',
      symbol: 'square',
      symbolSize: [30, 30],
      edgeShape: 'polyline',
      orient: 'vertical',
      expandAndCollapse: true,
      initialTreeDepth: 3,
      roam: true, //是否开启鼠标缩放和平移漫游。scale/move/true
      label: {
        position: 'top',
        rotate: 0,
        verticalAlign: 'middle',
        align: 'center',
        fontSize: 12,
        distance: 8,
      },
      itemStyle: {
        color: '#00ADD0'
      },
      leaves: {
        label: {
          position: 'bottom',
          rotate: -90,
          verticalAlign: 'middle',
          align: 'left'
        }
      },
      animationDurationUpdate: 150
    }
  ]
};
