After lots of tinkering I still couldn’t figure out how to change the colors, but have made some other updates.
This is a page on Grantland’s site that has a bunch of data visualizations for the playoffs. My favorite is the one at the bottom of the page which illustrates where the playoff teams make the most shots. You click on a team and the court changes. Blue means a terrible shooting percentage and red means great. The only problem I see with this map is you can’t make it bigger. If this went full screen or perhaps even opening up into a new window like other graphics from Grantland, I think it would have been a stronger visualization.
