Very interesting graphs, I was surprised that CSS has had a recent uptick but as somebody who has specialized in responsive layout in the past two years I guess that uptick represents my life too. I can't get enough language statistics on Github! I run 'gitinspector' on my web server to compute language stats in individual git repositories, but one thing I haven't been able to figure out it how to chart the language stats for one git repository over time in a branch. Does anybody know how you can chart language use over time in one repository?
