One of my professors in grad school was really into code visualization and we dabbled through a survey of the code viz approaches back then (~10 years ago now, geez). I do not visualize code. I did, once, in a way, but that faded... Any serious attempt to view code in a true multimodule/multithread/dynamic/static way to really _see_ the whole thing in toto takes us out of the Euclidian space we all wander in, to the _different_, tree based, non-linear space of a turing machine simulating some aspect of an extended lambda calculus (how extended? depends on your language). Code flows into and out of data, closing, suspending, and continuing, on one or more processors on one or more computers, through dizzying heights of dependencies, libraries, networks, and languages. A Riemannian/Euclidian space is simply not the model needed to break into actual code viz.
