I don't know if the "The Nebraska Guy Ranking" this project uses is very useful, though. In particular the "depth" criteria doesn't make much sense to me, since it assumes the more foundational a dependency is, the more robust it must be. This seems to run counter to the point of the original comic where the "Nebraska Guy" piece was the fragile block holding up the entire tower.

This project also doesn't attempt to measure or visualize the complexity of a project. Theoretically a more complex project would require more support than a simple one, so I think that's an important metric to capture.
