echarts官网，地理位置/地图（https://echarts.apache.org/examples/zh/index.html#chart-type-map）
基于“香港”示例，进行中国地图的展示
1、下载中国地图的json文件，并引用
https://datav.aliyun.com/portal/school/atlas/area_selector
import mapData from '@/utils/chinaMap.json' const geoJson: any = mapData
2、地图注册的名称首字母使用小写（如果大写，看不到南海诸岛简图）
echarts.registerMap('china', geoJson);
3、使用简图之后，删掉json文件中详细的坐标内容
4、隐藏海南省的坐标
修改如下：
