I started this page when I noticed that NYC's daily update used to have a "new cases per day" series in the main "total cases each day" graph, and then "new cases per day" disappeared. I started making graphs of "NY State - New Cases Per Day". I haven't updated it in a couple of days and I'm not sure how useful it is.
I found this site has a lot of good graphs for comparing different regions to each other -- with the caveat that the author isn't a subject matter expert and doesn't provide much commentary himself.
Last few days I've been avoiding trying to understand much or make any predictions.
