效果图：

一、获取市的地图数据

DataV.geoAtlas 获取市地图数据

点击地图缩放至想要的市区域，通过右侧的链接打开网址，复制json数据。

二、获取镇地图数据

选择你想要的镇数据，点击下载

选择级别（清晰度）

三、合并市和镇的数据

通过 合并转化数据（geojson）geojson.io 网址合并json数据

首先将市json数据复制到这里

然后通过 open 打开镇文件夹中的 .kml 文件，即可实现镇和市的合并json操作

最后将合并好的json数据放到 map.json 文件夹中等待使用

将 json 数据复制放进Vue 项目的 /static/map.json 地址中

下载 echarts ：

npm i echarts --save
npm i axios --save

main.js 注册

import { createApp } from 'vue'
import * as echarts from 'echarts';
import './style.css'
import App from './App.vue'const app = createApp(App)
app.config.globalProperties.$echarts = echarts;app.mount('#app')

组件内使用：

<template><div class="map"><div class="map_chart" ref="map_chart"></div></div>
</template><script>
