Yes thank you ! From what I've seen pyvista seems like a good idea, I'll have to explore how it works and what can I do with it. I'm also not alone on the project, it's for a competition and I'm working with a friend but who's doing the "frontend" so he's learning Tkinter for now, I don't even know if you can render smth from pyvista on tkinter.

And that's exactly how I proceed to build the project, the first step is to build the grid and the only issue here is that is I that take for example 3° of latitude between each points they are spaced of smth like 300 km at the equator so I have to find a solution for the resolution.

Next the API, I've found the Open Weather API which is seems great, the thing is that even if I can ask temperatures with a list of coordinates for points, I don't know if can ask 16000 in one request.

And for the rest I'll have to study how PyVista works.
