Images of the skill tree and map in Watch Dogs have leaked. It's Dual Shockers who have the images that origin from a livestream of the PlayStation 3 version (which may explain the low image quality). And they're in Spanish, but it should give you an idea of what to expect from the skill tree and map.
Watch Dogs will see release on PC, PS3, PS4, Xbox 360 and Xbox One on May 27, the release date of the Wii U version is still undecided.
Update: Turns out it's not Spanish, but rather Portuguese. Even less spoilers, then perhaps.
