What software was used to create the diagrams in the Git Community Book? [closed]
The diagrams in the Git Community Book are excellent and I'd like to know what software was used to create them. I emailed the author, but he didn't respond, so does anyone else know?
(This question was raised by request within this stackoverflow answer).
yEd is a powerful and free graph editor that produces really nice graphs.
I use it often for my needs. It provides automatic layout and many shape / line options.
These graphs could have been produced by this program.
