I've been plotting Wisconsin's covid data since March 2020. The plot I find notable right now is my plot of the two week rolling average of the two week percent growth. It's basically the rate of change of infections.
The previous highest value was 6.2%, literally the first day on my plot, April 11, 2020. That was broken Tuesday, and yesterday is at 7.1%. During the lead up to our biggest infection spike the growth peaked at +5.2%.
