Echarts Map usage Experience-map warp and add data

About the use of ECHART2,ECHART3 maps a little bit of life experience:
1.echart3,echart2 load Map deformation repair.
Recently, when using ECHART2, it was found that loading a map of Hainan would produce deformation. For example, the map of Hainan has a large deformation, so we need to study how to eliminate the deformation. After a toss-up, modify the _gettransform function in the Echart-all.js

varxScale = width /mapWidth;varyScale = height / mapHeight;console.log(rate);if(xScale > yScale) {     //xScale = yScale * rate;      xScale = yScale;      width = mapWidth * xScale;}else{      yScale = xScale;     //xScale = yScale * rate;     height = mapHeight * yScale;}

So the map can not be deformed (echart3 add this aspectscale:1 can make the map does not deform)

Add Custom Geosjon in 2.echart2 (mainly Echart2,echart3 Geojson is more convenient)
Also modify the Echart-all.js code to add the following code, you can use Maptype as ' Hainan ' map

‘hainan‘: {getGeoJson: (function() {       return function(callback) {$.getJSON(‘data/hn.geojson‘,callback);}      })()},
