Vue+Echarts 实现中国地图和飞线效果

实现效果

在这里插入图片描述

准备

高版本的echarts，不包含地图数据，需要自己下载到项目中

1、地图数据下载

https://datav.aliyun.com/portal/school/atlas/area_selector#&lat=30.332329214580188&lng=106.72278672066881&zoom=3.5

2、注册地图到echarts中

//根据自身情况，粘贴来的数据放在哪里就从哪里导入
import chinaMap from "@/assets/map/china.json";//注册地图到echarts中  这里的 "china" 要与地图数据的option中的geo中的map对应
echarts.registerMap("china", { geoJSON: chinaMap });

为了能复现效果，给出了项目的完整结构和完整代码

ChinaMap.vue

主要有3个部分：地图、线条、点
