Add graphs

[apaszke]

How about adding some pretty graphs like in: http://stackoverflow.com/a/9074343? It's a really nice way to see you repo status.

This is a nice idea. Will add this to the TODO and keep this issue open for idea discussion. 👍

Altho it would add to more complex stuff. It would be nice to be able to specifiy the colors used in such output.

Perhaps an optional config file would do the trick?

I feel like anything too complicated would take away from the drag-and-drop simplicity of Git Goodies.

A completely optional config would be wonderful for this idea.
