It's the usual "A contains B" relationship. At the top level, the entire project contains everything else, so there is one big box with many boxes inside. Usually, the next level is folders, then files, then classes and methods. But at the classes level, it gets tricky. There's syntax hierarchy, when class A contains method B, and there's logical hierarchy, when we know that in a working app, class A is the owner of class B, meaning that an instance of A creates, manages the state and destroys an instance of B. The visualizer needs to somehow account for this or let the user specify this relationship.

I think that a 3d webgl visualizer would be cool, but a graphviz style diagram generator would make money.
