I see. So he did something like git shortlog -ns --since="Jan 2010" (except that doesn't match the graph, so there's also probably a --before that should be added), and then removed the names and plotted the numbers against 1, 2, 3, .... I think I would have gone with lines added/deleted instead of number of commits, but still, I think you would see the same patterns.
