Echarts展示地图

效果图

安装

npm install echarts

默认安装的是 5.x 版本

在这个版本中的引入方式必须是下面这种方法

import * as echarts from 'echarts'

源码

在echarts5.x版本中，已经不再提供地图数据，所以需要我们自己手动下载，我这里已经提供好了下载地址

提前准备好地图数据 china.js

下载地址：https://szx-bucket1.oss-cn-hangzhou.aliyuncs.com/picgo/china.js，打开这个地址，然后 ctrl + s 保存就可以了，在浏览器中看到的是乱码，不要担心，不影响使用

然后下面是地图实现源码

<template>
  <div class='h-full flex justify-center items-center'>
    <div id='mapDom' class='h-full w-full'>

    </div>
  </div>
</template>

<script setup>
import { onMounted } from 'vue'
import * as echarts from 'echarts'
import '../assets/china'
import { getCityPositionByName } from '@/assets/cityPostion'

// 模拟10条数据
let mockData = [

onMounted(() => {
  let data = mockData.map(i => {
    let cityPosition = getCityPositionByName(i.name).value
    return {

      value: cityPosition.concat(i.value),

cityPostion.js 文件代码，这个文件主要是通过省份名称获取经纬度
