使用Echarts实现中国地图

1.Echarts官方地图资源

Echarts官方文档已经暂停了地图数据的下载，但是百度Echarts给我们留了下载的官方接口：https://echarts.apache.org/examples/vendors/echarts/map/

(1)JSON格式

https://echarts.apache.org/examples/vendors/echarts/map/json/

(2)JS格式

https://echarts.apache.org/examples/vendors/echarts/map/js/

2.实现

(1)下载china.js文件

https://echarts.apache.org/examples/vendors/echarts/map/js/china.js

(2)放到对应的文件(放在了utils里)

(3)上代码

<template>
  <div class="managingPatientSize">
    <el-row>
      <el-col :span="6">1</el-col>
      <el-col :span="12">
        <div id="china-map"></div>
      </el-col>
      <el-col :span="6">1</el-col>
    </el-row>
  </div>
