Grades for each state (and district) based on how badly the district shapes seem gerrymandered.
Click on a state to see the individual district grades. Click on any district to return to the state view. Click and drag to pan, and scroll to zoom.
To compute a district's gerrymandering score I use the ratio of a district's area over the area of its convex hull. A district is only penalized for other state districts intruding into its convex hull. Coastlines and state boundaries don't affect the score.
The code used to generate the scores is available on github.
