62 years of Congressional cooperation in a single gif


NPR's Science Tumblr Skunk Bear created this cool data visualization based on a study of the rise of partisanship in the U.S. House of Representatives:

Each dot is a single member of the House of Representatives (democrats = blue, republicans = red). The proximity and lines between dots indicates cooperation – voting the same way on legislation. The more they vote the same way, the thicker the connecting lines and the closer the dots.
