Deep dive graph for State-wise No. of Tests

[saberprashant]

Is your feature request related to a problem? Please describe.
No. of tests plays an important role in understanding the spread, so for a deep dive, there should be one Statewise graph showing no. of tests done.

Describe the solution you'd like
A graph which will show no. of states just like we have for "States - Total Cases" in Deep dive in a bar graph format showing the no. of tests done each day.

Describe alternatives you've considered
If we don't have tests done data for each day, then we can show only total no. of tests done for each state.

Additional context
This will help to get a deeper insight on how the testing process is going.
