调用百度 Echarts 显示重庆市地图

因为 Echarts 官方不再提供地图数据的下载，在这里保存一份，供日后使用，重庆地图数据的 JSON 文件在 CSDN 上下载。

这里写图片描述

值得注意的是：这里使用了 ajax 异步请求，需要将项目部署到服务器上才可以。另外可以采用 js 形式的地图文件，不用采用异步请求，打开 html 文件即可访问。

项目上传到了 CSDN ，下载地址为：Echarts重庆地图

全国各省市、曲线地图数据。下载地址：http://www.ourd3js.com/map/china_mapdata/mapdata.zip。利用这些数据做的全国GDP数据图：http://www.ourd3js.com/collection/xunmeng/GDPMap/index.html
