I extracted the Ciovid-19 statistics from Johns Hopkins University (JHU) . There are raw data for confirmed cases and deaths by date for each county in each state. For each state, I also extracted state population, area and population density from https://www.states101.com/populations. I wrote a Perl script covid-us.pl to gather the above information and cast it in a suitable form for the www.charte.ca motion charts and correlation data.
