How to do a timeline graph similar to GitHub using D3?

Question

GitHub uses D3 library for its graphs but I can't find any sample similar to how GitHub deals with timeline.

GitHub allows the user to select a particular period in time within the graph and then it shows data specific to that period.

Any example of the "period selection" ("brush") with D3?
