I've been fiddling a bit in R with a few plots similar to this and there are some things where you need to do manually assign or adjust (or maybe I don't know ggplot enough yet, 😅), but it's not that hard to get to a similar plot (not as good, though). I wanted to - and I think I succeeded in - create a template for quickly comparing series from different geographies using "small multiples" and I like the result so far. If you want, see link for my result:

Thanks!
