Plot Of COVID-19 Confirmed Cases In Ohio By Population Density

I was curious whether population density mattered in the spread of COVID-19. To answer this question I calculated the population density for every Ohio county and did a scatter plot of the March 26th Confirmed Cases. The three points on the right side of the plot are Cuyahoga(Cleveland), Franklin(Columbus), and Hamilton(Cincinnati) Counties. The exponential trend line looks like a pretty good match to the data.
