2024.5.27今天我学习如何用echarts做一个地图组件，效果如下：
主要三步：
1.获取地图JSON文件 （注意：该工具获取不到乡镇级别数据）
DataV.GeoAtlas地理小工具系列
2.引入该JSON文件并注册 （所有JSON文件我已经放入资源包，有需要的可以自行下载）
const xxx = require('@/utils/china.json');//引入
this.$echarts.registerMap('china',xxx);//注册
3.渲染图表
代码如下：
<template>
<div class="map_echarts" ref="map"/>
</template>
<script>
export default{
data(){
return{
china_data_list: [
