Cool! Is there somewhere a explanation what the "halth score" means?
The formula is a combination of: 40% - new cases / total cases (indicator of how much things are blowing up) 40% - absolute number of new cases (indicator for whether things are slowing down or not) 20% - recovered cases / total cases (indicator for recovery progress, although not all countries seem to post their recovery data)
The formula itself is somewhat arbitrary, but I felt it was a decently good metric that summarized the situation in every country. I'm open to suggestions on how to improve it as well!
