# this started out as an experiment, just trying to see what i can do
# with julia and some json.
#
# this will generate a graph of the times repositories of a user were
# created vs the last push times to that repository.
#
# it started out as a silly experiment that simply plotted two
# numeric/ordered values from the data, but it's quite interesting:
# quite a few users have this pattern where they constantly create (or
# fork) repositories and then move on after a while. for most people
# and projects we see a roughly linear increase, suggesting that people
# continue creating repositories on github and work a bit on them and
# then move on.
# still, there are projects that were started early and are still active,
# for example mbostock/d3 or my own heyLu/confidence (my dotfiles)
#
# next up: having fun with commits? (or activity?)
