I'm going to add a few more things here, but start with this:
Worldwide known #coronavirus cases and deaths by country: https://www.arcgis.com/apps/opsdashboard/index.html#/bda7594740fd40299423467b48e9ecf6
COVID-19 Daily Tracker by Andrew Lilley: https://rpubs.com/andrewlilley/covid19count
Interesting animated visualization aimed at showing when exponential growth slows: https://aatishb.com/covidtrends/ and a good video (if you like math) which explains the graph: https://www.youtube.com/watch?v=54XLXg4fYsc

A lot of great stuff here: https://www.businessinsider.com/coronavirus-in-charts-covid-19-symptoms-spread-deaths-warnings-2020-2#the-us-has-reported-over-1500-coronavirus-cases-3
This analysis MAY be overly optimistic, but I like the approach and it's useful to read to take a breath from all the panic out there: https://medium.com/six-four-six-nine/evidence-over-hysteria-covid-19-1b767def5894
