Rate of positive test results

Created by: akumar90

Is your feature request related to a problem? Please describe. Have a clear understanding on whether the increased number of cases is because of increased testing Vs. increased spread. As per WHO guidelines, if a positive test rate is greater than 10%, the country is not doing enough testing.

Describe the solution you'd like Understanding what the trend of rate of positive tests has been overtime.

Describe alternatives you've considered N/A

Additional context Having a graph similar to the active graph would be great. I am imagining the rate to be calculated as (number of positive results/number of tests)%

**Also working on creating something for rate of transmission of the disease. Will create a new feature ticket once I have requirements flushed out.
