Making Digraphs in Ruby

Digraphs (or "directed graphs") are a very useful tool for visualizing data.  It will generate graphs for visualizing a number of nodes and edges, giving you a graphical representation of "network" type data representations.  This can be used for hierarchies and tree structures, filesystems, you Rails models, or anything else with this type of relationship.  And it's all very easy to use, so why not generate graphs for everything?
