Astropy Sustainability Dashboard

Many <https://twitter.com/astrofrog/status/663390465295806464?s=20>_ of <https://twitter.com/adrianprw/status/991320279472377856?s=20>_ us <https://twitter.com/brettmor/status/1235224242117054464?s=20>_ within the Astropy project like to make figures that summarize the sustainability of Astropy for talks (e.g., citation rate over time, number of committers, etc.). This repository will generate those figures on a regular schedule for tracking, and for easy copy-pasting into talk slides and discussions.

This is very much a work in progress, but see some examples here: https://adrian.pw/astropy-sustainability

The goal is to move this into the astropy organization, but I am just prototyping ideas here!
