The true shape of the Midwest- Google Analytics

Maybe for some people who don't know the midwest as well as I do the google analytics visitor overlay map looks fine. However, the shape of my home state, Wisconsin, is certainly distorted and Michigan is almost unrecognizable. This overlay uses the states boundaries that extend over water. For most states that does not affect the overall shape very much but for the upper midwest it makes a big difference.

For reference, heres a google map of the same area.
