Benpian demo use leaflet api Echarts4 Migration in FIG binding function, the effect is as follows:

Realization of ideas: the leaflet to achieve binding Echarts4 scattergram (attached download source) based on the realization

• Map initialization

var Map = L.map ( 'Map' ); 
L.tileLayer ( '} http://map.geoq.cn/ArcGIS/rest/services/ChinaOnlineStreetPurplishBlue/MapServer/tile/{z}/{y}/{x ' ) .addTo (Map); 
map.setView (L.latLng ( 37.550339, 104.114129),. 4); // set the zoom level and center point

• Echarts related configuration options

var geoCoordMap = {
"海门":[121.15,31.89],
"鄂尔多斯":[109.781327,39.608266],
