终-Echart可视化学习（十二）

文档的源代码地址，需要的下载就可以了（访问密码：7567）
https://url56.ctfile.com/f/34653256-527823386-04154f

进入官网寻找

里面可以搜素很多

这里直接使用下面这个示例

gallery.echartsjs.com/editor.html?c=x0-ExSkZDM

可以看到源码

实现步骤：

第一需要下载china.js提供中国地图的js文件

第二个因为里面代码比较多，我们新建一个新的js文件 myMap.js 引入

使用社区提供的配置即可

我们之前已经引入了

在index.html加入容器

在index.js立即执行函数

实例化对象

指定配置，将前面官网的例子代码复制过来
