3rd suggestion - replaceu "limit to 200+" by a number/slider so user can set limit him/herself

2nd suggestion would be improved country filter. I can think of at least 2 options: by continent or by regular expression for country names. I, for example, would like to see situation in Europe

And thank you for great tool.

Could you add 5 or 7 day spread and acceleration?

The data you are using arrives at different times of day - it results in kinks/jumps.

Having the numbers for longer time period will smooth them away
