webinspect | Simple web server for inspecting incoming HTTP | HTTP library

The numbers you're interested in are updated by querying another source, so the page loads initially with the "Loading..." that you're seeing. You can see this in action if you refresh the page - initially, there's only "Loading..." in the boxes that's later filled in. The trick here is to find the source that supplies that information and request that, rather than the page itself. Here, the page that https://coronavirus.jhu.edu/ pulls from is https://jhucoronavirus.azureedge.net/jhucoronavirus/homepage-featured-stats.json, so we can query that directly.
