This Covid-19 tracker mashes up data from a few different sources to give views that aren’t found in the other dashboards already available. Especially helpful is the inclusion of the number of tests performed with detail down to the state level.
Data from Italy is also included, to provide a comparison to the western location that is chronologically in the forefront of fighting the curve. https://www.inetsoft.com/info/us_covid_test_tracker_dashboard/
