Ok, so I was a little bit bored and decided to plot all of the physics graduate programs and then assigned each school a standard Red to Green gradient based on rankings, where Green represents good rank and Red is bad.
In fact, It is set up so that pure Green (0,255,0) corresponds to a Rank of 1, (255,0,0) corresponds to the worst rank (anything at 145 or which US News didn't bother to rank) and each color in between corresponds to some discrete step of 1/145th.
This data allows us to more accurately plot the dead zones. Reviewing these plots is highly disconcerting because we can clearly see that dead zone is encroaching on the west coast much further than we had initially anticipated. If California, Oregon and Washington aren't careful, they run the risk of being being infested.
