These are screenshots from a web-map I made with Eurostat data from 2021. Of course the 3D-effect and the coordinate system handicap the idea on such a scale. But I think it still looks nice and there are some interesting discoveries (for example does someone knows why Puglia has so many spread out high spikes? I thought the region looses it's population for generations).

Note:
The height-effect varies from picture to picture because its linked to the scale.
The more North you go the more the projection distorts the picture. Thats why I didn't add a picture from Scandinavia.
I obviously didn't had data for some countries.
