http://91-divoc.com/pages/covid-visualization/
91-DIVOC is a site for creating daily time-series graphs for cases, deaths, and testing, both for daily counts and running averages. You can choose from different sources for data, use either linear scales or logarithmic scales, and create either static graphs or animated graphs. The data are available for the U.S. and globally and can be downloaded as .csv files.

The Financial Times makes available for free its interactive tool for visualizing trends in cases and deaths in COVID-19 cases and comparing them across countries. The site is noteworthy in part for its use of logarithmic scales to show how growth in cases/deaths increases or decreases.
COVID-19 Health Equity Dashboard
https://covid19.emory.edu/
This dashboard from Emory "seeks to fill the gaps in county-level data about the virus and underlying social determinants of health. Our goal is for this Dashboard to facilitate easy comparisons of counties with respect to COVID-19 outcomes and social determinants." Its focus is on how communities' experiences with the pandemic differ due to factors such as poverty, presence of chronic health conditions, segregation, or access to healthcare resources. You can create either statistical graphs or maps to make comparisons and look at relationships between COVID-19 outcomes and the social/demographic/economic characteristics of states and counties within the U.S. See https://covid19.emory.edu/data-sources to see a list of currently-available indicators and definitions. See https://www.cdc.gov/coronavirus/2019-ncov/community/health-equity/index.html for other resources related to disparities and inequality and their effects on local serverity in COVID-19 outbreaks.
