先来看最终实现的效果图：
想要实现各省市的行政区域划分图首先肯定需要有这个省市的数据，那么很多小伙伴可能就会问了：我没有啊，去哪里找？ 这就需要阿里云的数据平台了：datav.aliyun.com/portal/scho… ps:echarts实现的话记得选择“其他类型”，然后下载对应省市的json数据就好啦。
以下为代码实现（其实很多平台都有，这里不过是加了点特效）
//盒子
<div ref="echartsBoxMap" id="ArmamentariumMap" class="ArmamentariumClassMap"></div>
//js
import * as echarts from "echarts";
import "echarts-gl";
import elementResizeDetectorMaker from "element-resize-detector";//这个不需要的话可以不引用
import shandong from "../json/shandong.json";//山东
initMap() {
var myChart = echarts.init(document.getElementById("ArmamentariumMap"));
echarts.registerMap("山东", getData());
let data = getData().features.map((item) => {
return {
name: item.properties.name,
adcode: item.properties.adcode,
};
});
const points = [

大小调整zoom值，打点颜色什么的都可以在echarts官网找到对应配置项。 记得定义盒子的高度和宽度，不然无法显示。 大家再见。
