And the cool module of the day is Graph::Easy (live demo) by Tels++.
It's kinda like GraphViz, but it also supports various text-mode output formats.
That's very cool if you want to render a graph of, let's say an inheritance hierarchy in, let's say Emacs. Which I do.
Widen your browser window and take a look at this fairly complicated graph that it managed to deal with (ancestors of the class CatalystX::FeedMe::View::Atom (found at the bottom)).

It can even handle groups of nodes (with bounding boxes) and things I thought would be really weird in text-only.
The graph that I display in Emacs is actually quite a bit more compact than the output above. I munged the text a bit to make it fit in the Message window (all upwards arrows are removed since that's the most common inheritance relationship).

Hopefully that's about the most complicated structure I'll have to visualize.
