Overlay geo-vector-data on top of mesh in Blender

[RobinKohrs]

Sorry, probably this is the wrong place to ask, but I did not know where else I could ask...😬
I've seen some incredibly beautiful plots of you where there are lines (possibly geocoded like shapes, gpkgs, ...) on top of meshes in Blender. I am not super experienced with Blender but already invested quite some time to learn the basics. I'd love to create similar plots like this one:

But I just do not know where to start. Is it a good idea to use the BlenderGIS Plugin. I am not sure to be honest, but if it's not that I am even more lost on how to get vector-geodata into blender.
Maybe you have any idea on where to find ressources on that? Any advice would be super appreciated!
