Bundle View

I have grand aspirations for this code. For now: silly simple.

Prerequisites

Ruby Gems
Gem Bundler
GraphViz
ruby-graphviz gem
A project with a Bundler Gemfile. May I suggest a Rails 3 app?

Run it!

Either copy this file into a dir with a Gemfile or set the Gemfile path manually by assigning ENV['BUNDLE_GEMFILE']

What you'll see

Blue nodes: explicit requires from the Gemfile
Grouped dependencies in boxes (unless a dependency is in many non-default groups, GraphViz doesn't handle this)
Rectangle nodes: System Gems

Future

I have a lot of crazy ideas. No clue if this is going to become anything. But it's fun...

Turn it into an actual module, as opposed to just a bunch of ruby in a file
Turn it into an actual Gem. Seems appropriate.
Make it an extension/plugin to Bundler
Support exporting to HTML with embedded SVG...maybe with some hover effects, links to RubyGems.org for each package, etc.
Be slightly more robust about handling gems -> not just using their simple names
Show version info, etc. Version requested vs what was picked, etc.

Your ideas? Share!
