I like using graphviz for visualizing existing code and data. I write a script to generate the .dot file, maybe tweak it a little, and render with graphviz. I've used this for our data model, ER diagrams, jar dependencies, brew package dependencies, etc. For class diagrams, I have a little python script that takes a language like: Foo -> Bar Bar *--1 Baz Foo - name : String - flag : boolean And turns it into a diagram.
