I think it is this: for all the babies born in 2021 having a given name, the location on each axis is the percentage of those babies who are female in either the US or England/Wales.
So for example, for babies with the name Angel: in England/Wales, about 82% are female and in the US, only about 13% are female. In both locations, more than 80% of babies with the name Wren are female and fewer than 20% of babies named Dillon are female.
Some conclusions you could make: In England/Wales, Hadley is more likely to be considered a boy's name (just over 20% female) but in the US, Hadley is almost exclusively a girl's name (nearly 100% female). In both areas, Dillon is a boy's name and Wren is a girl's name.
