Now we are ready to extract the values from the raster layer at these points. Go to Processing ‣ Toolbox. Search and locate the Raster analysis ‣ Sample raster values algorithm. Double-click to launch it. Select 2018_Gaz_ua_national as the Input Point Layer. Select us.tmax_nohads_...
We only need two more steps to get faster and interactive map plots (plus background maps!): First, we need to reproject the lat/lon values. (There’s a warning here, most likely since some of the input lat/lon values are invalid.) Then, we replace plot() with hvplot() and voilà...

I use it a lot to view profil cuts/slices. It can also render in its 3D view a points and polygons from 3D shapefiles. It would be great if this future point clouds viewer could also display vectors and even raster for added context. I can't personally help with the backend ideas,...
