It's understandable that several places don't have data (NaN), but I found it curious that Burma/Myanmar is missing from the map [1], much like the "Poland Sea" in a Microsoft Date/Time screen from yesteryear [2].
Did you create this map data or get it from somewhere else? Is this some kind of joke?
No, it's just a bug. I have been using two sets of data where the name of the countries were not perfectly matching (example: United States VS United States of America). I fixed most of the inconsistencies and showed the map to some people to help me spot the problems. This one slipped through (as the geocoding of Serbia and some NaN).
