As longtime readers of this blog know, the editors of the World Almanac are suckers for data visualizations of any and all varieties. I especially enjoy this map of the United States, with state border lines redrawn in favor of a more population-based border determination: baseball team loyalty. It may not be as data-centric as the maps you'll find in the World Almanac, but I'm a baseball fan, so I think it's pretty cool. Though it may have missed the mark in some places: Do the Washington Nationals really have more Maryland-Virginia area fans than the Baltimore Orioles?

Comment to let us know how well it represents your local loyalties. Do our nation's redrawn borders hold up?
