Source for case numbers: ulklc/covid19-timeseries on GitHub (which itself lists its primary sources)
Plots by Chris Billington. Contact: chrisjbillington@gmail.com
Python script for producing the plots can be found at https://github.com/chrisjbillington/chrisjbillington.github.io/blob/master/covid.py. The script is messy, as things are in a state of flux and I've been experimenting and switching data sources. It will likely be cleaner once it becomes clear which data source is best.
