I’ve made a dashboard for tracking COVID-19 cases by country and by US state. (seems to be one of many).
The app uses the data from the Johns Hopkins Github repository, and provides views of total cases, active cases, recoveries and deaths.
Additionally, there is a view of new cases vs total cases, which is designed to clearly indicate whether the growth of cases is in an exponential regime or not. (Inspired by this minute physics video)
