Interestingly this uses JHU data [1] (with lag because they don’t push in real time), yet somehow managed to omit part of the data, e.g. 8k cases in South Korea completely missing.
I just fixed it, there was a problem with the map.
Anyway, the data are pulled from the original repository three times per day to avoid too much traffic. I will try to increase the number of updates :)
