Statistic is kinda weirdly chosen: 200 men : 100 women is the same as 100 men : 50 women, yet the graphic would treat one of these as twice as extreme as the other (+100 vs -50).

Granted, for values close to 100 this doesn't distort much.

Clarifying example:

For example, suppose we had 100 men and 100 women distributed in 2 countries. If we put 60 men with 40 women in country A and 40 men with 60 women in country B, this statistic would report: A: 150 men : 100 women B: 67 men : 100 women

And it would color the excess of men a darker blue than the excess of women (because one is +50 from 100, while the other is -33; note the spacing on their gradient). This would make it seem like there’s net more men than women, which is not true.
