I'm not a stats expert, and this is a genuine question rather than an accusation. I notice on the "graphs" page, the trends look very close to perfect exponential curves when China is excluded, but get a lot further from that when China is included. Does this suggest a lack of accuracy in the numbers they've reported, or is it more likely that the government's strong reaction to the outbreak quelled the exponential growth in a mathematically disruptive way?

Great question - I have heard both of the options you mentioned as possible explanations for the decline of new cases.

Personally I like to give countries the benefit of the doubt. As difficult as it sounds to quarantine and stop the spread of a virus in a country with 1+ billion people and multiple 10M+ cities, China is one of the few countries that could actually pull it off.

At the end of the day, the option you pick probably depends on whether or not you trust the numbers provided :)

Can you add the copyright attribution to the map (Mapbox, OpenStreetMap it seems) or at minimum on the /about page? It's part of their terms of service and not optional.

Very good point - the attribution has been added. Thanks!

Cool! Is there somewhere a explanation what the "halth score" means?

For a site focused on "clarity", I sure didn't make the formula very clear :) I will work on clarifying it on the website.

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!
