Visualizing the rate of change for COVID-19 cases in the U.S.

Updated March 31st

To understand what is going in the United States with the recent outbreak, it isn’t enough to look at just the cumulative number of cases or deaths. Here, I’ve created a visualization that allows you to simultaneously view the cumulative total, the derivative of the cumulative total (i.e. the daily increase), and the derivative of that derivative (the rate of change of the daily increase). Click on the table headers to sort the data.
