Red and blue is so obvious for girls and boys, so I really wonder what made someone deviate from that??
Yeah I can't read the charts at all.
Came here to say the same. Anyone doing data visualization should think long and hard before using something beside a line or bar chart. Almost everything else is worse in multiple ways.
If they used these chart types, though, it would be too obvious that the data doesn't tell the story they want it to!
