Deck.gl GPU Heatmap
A continuous heatmap rendered entirely on the GPU — points are splatted into a Gaussian intensity field and the field is colour-mapped through a perceptual ramp on every frame. Because the splatting and accumulation run on shaders, hundreds of thousands of source points still ren

When to use this template
This visualization reveals the continuous density of a large number of points across a geographic area. Analysts use it to understand where events are concentrated and how their density changes smoothly over space, prioritizing the overall shape of the distribution rather than exact counts in specific bins.
- Geospatial point data with very high cardinality.
- Datasets where individual point locations are less critical than overall density.
- Analyzing smooth, continuous distributions rather than discrete counts.
- Exploring spatial patterns that remain legible across zoom levels.
- Data where the intensity of events varies gradually across space.
- Identifying hot spots and sparse areas in large point clouds.
