vue中，基于echarts 地图实现一个人才回流的大数据展示效果
0.引入echarts组件，和中国地图js
import eCharts from 'echarts' import 'echarts/map/js/china.js'// 引入中国地图
1. 设置地图容器
<div id="ID_L2H1Map" style="width: 600px;height:400px;"></div>
2.调用echarts绘制地图
createEchart_2L1H1G (data) {
data = [
{ "name": "北京", "dataCount": [0, 1, 0, 0, 0, 0, 1], "id": "247" }, {
