What graphing library does GitHub use on its Graphs tab? When you navigate to https://github.com/USER/REPOSITORY/graphs/commit-activity the graphs are clean, beautiful, and responsive. If they are using an open source javascript library, I would love to use it as well! I have not been able to tell from a brief code inspection.
The new GitHub graphs are built with the amazing d3 library by @mbostock.
