When codes are added, the existing area code tends to stay with the major population center. For example, Washington’s 206 is now just for Seattle. The same happened with 801 for Utah/Salt Lake City, 612 for Minnesota/Minneapolis, 503 for Oregon/Portland, etc.
Eurasia looks like a Muppet tadpole from a bad dream.
It would be interesting to find a way to also represent the overall rate. Some of these countries really stand out for their high male:female ratio even though their overall rates are not particularly high.
