Generate graphs of the partials your Rails app uses
$ gem install giraffe
g = Giraffe.new("/path/to/app/views") g.generate("graph.png")
Or, more succinctly:
$ giraffe /path/to/app/views/ graph.png
It's pretty naive at the moment, doesn't deal with anything other than partials included by name etc…
Could do with being a bit more intelligent.
