It's a divergent color scheme, and it looks wrong because it's usually used to illustrate how how data diverges from a midpoint (ex: voting patterns). They should have used a sequential scheme of a single color since it's numerical data - dark hue for high values and light hue for low values. It's maps 101 and this is dumb.
Edit: also lol @ that data range.
