This isn't exactly specific to Michigan, but it's a really cool dynamic graph produced with Tableau software. Simply click on a team on the top bar to view their recruits, what state they came from, how many stars they had (based on Rivals' data), etc.
For those of you who don't know, Tableau is a very useful data visualization tool. I'm an analytic consultant and we use it all the time for displaying data in an easy, digestible way to our clients. I've never seen anyone use it for public-type work, but is by far the coolest thing I've seen it used for.
Also note, I did not produce this graph. This particular graph was published by a fellow named Scott Wasserman.
