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?
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.
