Just for fun, let's draw a tennis court.

Following up on my post about partisanship in the 111th US Senate, I wanted to look at how alliances have shifted over the history of Congress. Use the buttons below or the left and right arrow keys to move back and forward through Congresses, and you'll see parties and legislators move across the political spectrum.

The best dataset to understand political polarization is Voteview's DW-Nominate scores. I'm only looking at the Senate here, both to reduce the numbef of points and to make it easier to chart the first time. My goal is to eventually plot every congress and see how alignments have shifted over the past two centuries.

tl;dr - Yes.

Making a few circles here.

In which I attempt the first two [D3] tutorials.

Well, hello there, world.
