chfw opened a new issue #10667: Hard coded center point for Russia and United States
URL: https://github.com/apache/incubator-echarts/issues/10667
 
 
   ### Version
   4.2.1
   
   ### Steps to reproduce
   https://echarts-maps.github.io/echarts-geomapping-book-zh/intermediate/change-world-center/
   
   In short: world.json is re-projected using eckert3 and rotated -150 degrees, then country names 'Russia' and 'United States' appears in the "sky".
   
   And you can view it here and scroll all the way to the bottom, look at eckert3-world.js:

   ### What is expected?
   Country names, 'Russia' and 'United States' will appear on top of their country region.

   ### What is actually happening?
   Both names appears on the top left corner.

   This is caused by https://github.com/apache/incubator-echarts/blob/master/src/coord/geo/fix/geoCoord.js.
   
   ```
   var geoCoordMap = {
       'Russia': [100, 60],
       'United States': [-99, 38],
       'United States of America': [-99, 38]
   };
   
   export default function (mapType, region) {
       if (mapType === 'world') {
           var geoCoord = geoCoordMap[region.name];
           if (geoCoord) {
               var cp = region.center;
               cp[0] = geoCoord[0];
               cp[1] = geoCoord[1];
           }
       }
   }
   ```
   
   Of course, the workaround is to change the country names to something else for now, but hard coded fixes shall NEVER be there in CODE.
