Maplibre Globe

"""
GlobeView
=========

Over 33,000 power plants of the world plotted by their production capacity (given by height)
and fuel type (green if renewable) on a MapLibre globe view.

This example demonstrates using MapLibre's globe projection with deck.gl layers by setting
map_provider='maplibre' and map_projection='globe'. The globe view uses MapLibre's
MapboxOverlay with interleaved rendering for optimal performance.
