Is this Covid-19 deaths in the US or the world? Might make sense to mention that somewhere
You're right. I just updated it to mention that this is US data. Additionally, I added a link and timestamp to the CDC data that drives this. This way it's not just another site of unsourced information.
This is a minimalist site that I made to create a real-time comparison between 9/11 and the current COVID crisis. PR's and feedback are more than welcome!
