The image above shows one of the graphs we tested Graphy’s step-by-step visualization expertise on; I never thought a depth first search would look that cool. Get Graphy!

GraphML With JUNG: Saving Out

This one of two posts I’m dedicating to saving out to and loading from GraphML using the JUNG library. These are two parts of a really good library that lack sufficient documentation.
