Graphviz is very useful for visualizing large graphs. You can learn to use it effectively in under five minutes. It's also very easy to transform CSV data into graphviz markup by piping it through one or two sed scripts.
Where can you learn to use it effectively in under five minutes?
Assuming you have dot installed:

Also, these are useful:

Another good example is in the book Land of Lisp. Chapter 7 and 8 makes a game, Hunt the Wumpus, using Graphviz:

Chapter 8 is even available as a free download:

The visualizations of processes are crucial to my understanding of Brendan's analysis. As a visual person, I can't imagine using this data another way.
Once again we see that screen size remains a central UI limitation to better UX. Give me a wide printer and a big wall any time!

We're actually planning to print some of those at full size as office decoration.
I've made something very similar, but using Ubigraph and for Python: http://www.youtube.com/watch?v=v2kyssgtUvM
Looks very nice - I'd love to do something like this for Lua. I went looking for more details, but it looks like your blog is down, alas .. anyway, if there is already something out there on the subject of using Ubigraph, tutorial/howto-wise, I'll go looking for it. It'd be great to have something like that when debugging a large Lua project.
Really neat.
