This is a set of simple (for now) ROOT macros to utilize public COVID19 data.
The dataset (time history for each state) is downloaded from @covidtracking via https://covidtracking.com/api
It runs several shell scripts to massage the file into a useful form for ROOT to read-in. Works so far for me on Mac OS X with zsh, bash, tcsh, & csh.
Variables are listed in the source, but explanations can be found at the link above.
Example:
root [0] .L covid19_tree.C (load the macro)
root [1] TTree* cv19 = covid19_tree() (download the data and create the tree - US only - from COVID19 tracking)
