Is there anywhere (global) data about total number of tests made? The plain number of positive cases is quite difficult to make sense of.
They also have the dataset available as a spreadsheet or a JSON or CSV API:

The project was started by some journalists from The Atlantic. Seems to be a lot of duplicated effort in this area, although perhaps they are sharing data.
The key metric is tests/confirmed case.
When I've looked, this is very predictive of confirmed cases (2 weeks ago) per death.
