LeaFlet遷徙圖的製做
前言：在arcgis openlayer 都會用到遷徙圖，這些圖都是爲了展現一些是數據所須要的，作了一年的gis開發，給個人感覺WebGIS始終圍繞的是對數據的展現，並非側重於數據的深挖掘，WebGIS在分析上還欠完善，我的認爲，如今的WebGIS仍是查一查，看一看，和前幾年的三維可視化差很少，廢話很少說，說到用到展現數據，echarts是一個很好的工具，讓leaflet和Echarts相結合，css
下面是個關於插件的地址：https://github.com/wandergis/leaflet-echarts3html
1、來張圖git
效果並無太炫酷，能展現數據，達到預想的效果便可。github
2、所有代碼web
