And if anything, the scatterplot put up by fransknorge is actually sort of useful for figuring out where to go (or not go) -- if you're allowed in -- during the winter in this year of a pandemic.

It would be interesting to see how that scatterplot overlays with a scatterplot for changes in hotel's average nightly rates by country during this pandemic period. That might be useful to land some travel bargains or other acquisitions for an even more extreme discount.
