This is a network visualization of current NCAA FBS head coaches, offensive coordinators, and defensive coordinators. Graph edges represent two coaches coaching on the same staff at the same time at some point in their career. Hover over a node to see who it is, and to see other coaches that coach is connected to. The graph can be dragged (click and drag), and zoomed (double-click to zoom in, shift-double-click to zoom out). Thanks to Wikipedia for the data, and to Paulo Villegas for most of the code.
