Numbers and colorful graphics

Quoting @plehegar from #27 (comment):

there is value in surfacing those numbers to the Groups. Numbers and colorful graphics do help surfacing issues in general and educating the community at large

Philippe, did you have this repo in mind as the place for this, as a sort of dashboard? Beyond pull request stats, are there other statistics you think are important and well suited to visualization?

this is the best place I can think of for this for now. we already have graphics for issues.
