what should be plotted? describe and assign.

Good point, we could start with the reporting you see in the Readme, specifically the first "Repo changes (inserts and deletes) per week" one. Does that help?

I am also open to adding more metrics to make this more interesting, any ideas? If so let's open one or more new issues for that.

I wrote this beginner article on plotext the other day btw: https://pybit.es/articles/terminal-plotting-with-plotext/
