This is a map of US wind speeds, and can be found on the NREL website.
The colors are a very nice and easily seen on the white background. The map itself is big enough the each state is clearly defined. Though the map itself doesn't have a title using the legend it's easy to tell what the map is and at what speed the winds are. It doesn't have any scales so you can't tell if they are and adjusted size or not. The point of the map is very clear and everything is very readable. This is a good map it is very simple but it gets it's point across.
