Is your feature request related to a problem? Please describe. For a desease like covid19, we need to make use of every analysis possible. It would be great to show a daily growth factor of the disease in a map.

We can have a drop down to select daily growth factor of new cases, daily growth factor of deaths.

Daily Growth Factor of New Cases = Total new cases of yesterday/ Total new cases of today

Daily Growth Factor of Deaths = Total new deaths of yesterday/ Total new deaths of today
