Deck.gl Extruded 3D Polygons
3D extruded polygons drawn straight out of the map plane — every footprint becomes a building-shaped solid whose height encodes a value (population density, building height, sales-per-zone, anything quantitative). Deck.gl's PolygonLayer supports complex polygons with holes, per-p

When to use this template
This visualization makes it straightforward to compare quantitative values across distinct geographic regions by rendering them as measurable 3D solids. It enables analysts to quickly identify spatial patterns, concentrations, and outliers, providing an intuitive sense of magnitude and distribution for a given metric across a defined area.
- Geospatial data with well-defined polygon boundaries.
- A single quantitative metric associated with each polygon.
- Data where the magnitude of a value needs clear visual comparison.
- Datasets requiring perception of relative 'volume' or 'intensity' per area.
- Large numbers of polygons benefiting from GPU-accelerated rendering.
- Data where a third dimension enhances spatial pattern recognition.
