View version control progress graphically

Is there a software for mac that lets me view the progress of the branches in either git or svn like in thi开发者_Go百科s image (from here)

Git Web Access implements a new kind of visualization which is inspired by schacon's drawings in ProGit.

Note: Although not a desktop application, it should work on a Mac (with some help from Safari) ;-)

See below an example:

Not to the level of the above given picture, but I find git log --graph and gitk to be good enough visual indicators.
