TPM put together a number of graphs comparing the NYC metro area to the rest of the country in their article Distinguishing the NYC Metro Outbreak from the Rest of the Country by Josh Marshall (5/6/2020).

The data for COVID-19 deaths by county in the U.S. from Johns Hopkins is here. The data is updated daily.
