Author here. I know I posted this a week ago, but I've since added more functionality (e.g. the ability to compare countries from the date when the disease reached 100 cases in each country) that should make it more useful, so I hope this is okay. I truly believe this could be a helpful resource for some people (on the Johns-Hopkins dashboard, Worldometers and lots of other sites you cannot easily select and compare countries). I also put some work into making this mobile-friendly. A friend of mine who runs clinical studies said "This is better than every other solution/dashboard out there!", and I'm glad if it helps more people to understand the infection numbers in different countries.
Feel free to provide feedback and improvement suggestions, I plan to add more functionality in the upcoming days.
