vue echarts 中国地图处理南海诸岛为简图

1.下载中国地图的json文件

中国地图json文件      <=访问这个网址，进入下图页面，选择图中标记的按钮，下载成功后的json文件为中文名称，将其改名为china.json

2.将json文件引入项目，展示效果如图

问题：

南海诸岛多占区域较长，视觉效果不好，期望在右下角出现南海诸岛的缩略图

解决方法：

1.显示南海诸岛缩略图

        问题原因在于地图注册的时候，China的首字母大写，改成小写，就会出现缩略图

        修改之后的效果图：

2.隐藏边界线

        json文件中，删掉下面所示代码

        删除之后的效果如下：

3.隐藏南洋诸岛

        这些岛屿都属于“海南省”，所以找到json文件中的“海南”，将其中的“coordinates”替换成下方代码：
