bcpelletier commented on issue #11420: Programmatically selecting countries 
with geo and map series
   I will try to explain.
   The functionality would be to allow to select and deselect countries 
modifying the underlaying data.
   In the case you have a "normal" map series e.g
   Series: [ {
   name: 'UD',
   type: 'map',
   map: 'world',
   data: [ { name : 'Spain', selected : true}] 
   The map would load with a country selected, in this case, Spain.
   But, if we have a series that references a geoIndex, echarts does not use 
the selected parameters and does not "pre-select" Spain
     geo: {
     map: 'world',
     roam: true,
   Series: [ 
   geoIndex: 0,
   data: [ { name : 'Spain', selected : true}] 
   Btw if geoIndex is used there isn't any way of selecting a country 
programmatically, "mapSelect" action doesn't work and "highlight" action works 
but "deselects" once resize() is called (kind of useless imo)
   So at least this would allow to re-merge the data with selected so the map 
can be controlled apart from the end user "clicking" on the map.
   Hope that I have explained myself.
   Thank you.
