Deck.gl Screen-Space Grid
Screen-space density binning — instead of binning into geographic cells (which become tiny when zoomed out), Deck.gl's ScreenGridLayer bins into pixel-sized cells in the viewport. As the user zooms out, the cells stay the same pixel size and the density inside each cell grows; as

When to use this template
This visualization makes it easy to identify spatial density patterns and hotspots in very large point datasets across all zoom levels. An analyst would use it to understand where events or entities are most concentrated, especially when the sheer volume of data makes fixed-grid geographic binning impractical or misleading at different scales.
- Datasets with millions to billions of individual geospatial points.
- Data where the primary insight is the spatial concentration or density of events.
- Point data spanning vast geographic areas, from city to global scales.
- Scenarios requiring dynamic aggregation that adapts to the current map viewport.
- Data where individual points are too numerous to render effectively.
- Time-series geospatial events where density changes over time are key.
