COVID-19: Daily change

New daily infections (daily change) of COVID-19.

The chart shows new daily cases across the entire planet, the US, EU (de+fr+it+es only) and a small country (RO) that does not matter to anybody but me. You can show/hide different country in Settings.

Select "COVID-19: CONFIRMED" data in main chart and add the indicator.
