Great style and animation, good work!
A couple of issues that came up for me:
The divisions within countries seems a bit weird. For example, England, Italy, and Germany are split up into provinces/counties, but then Ireland is just split into south/east/west (which are not real regions), while France, Scotland, Whales, Northern Ireland, and all Eastern European countries are not divided at all. That’s just Europe, similar odd divisions seem to occur on other continents too. Is this something to do with the data set you are using?
I’m also trying to make sense of the coloring. It seems like dark blue is relative to the total worldwide number of cases, or perhaps the country with current highest cases? It makes it a little hard to track for one country. Again, focussing on Ireland, when I zoom over the country, it’s hard to see the height map since I’m directly above, then if I select total cases and play the timeline, it appears like the country is getting a lighter shade of blue as number of cases increasing, when I would expect it to get darker. I’m not sure what a good solution is here, but this seems a little hard to interpret, currently. Maybe make an option to have coloring relative to the country, or add another shade so that the highest overall is a red tinge while per country is blue? Than as the cases within a country get higher it will continue to increase in color even while other countries take over.
