Decide when to enable native GeoJSON clustering in Mapbox GL JS, how to style clusters, and how to validate click and performance behavior.
A technical guide on choosing between GeoJSON and Vector Tiles in Mapbox GL JS to prevent browser lag and optimize.
Client-side clustering in Mapbox GL JS is a source option, not a layer trick. The three-layer pattern, click-to-expand zoom, clusterProperties aggregates, and when vector tiles are the better call.
Mapbox GL JS can cluster thousands of points entirely in the browser with cluster: true — no server required. Here's a working setup, the click-to-expand pattern, and the dataset size where you must switch to server-side aggregation.
Step‑by‑step guide to load a GeoJSON point set into Mapbox GL JS and style circle radii dynamically using a data‑driven expression.
Learn how to enable client-side clustering in Mapbox GL JS to render thousands of points efficiently, with a code example and performance considerations.
Learn how to implement client-side point clustering in Mapbox GL JS to handle high-density datasets using GeoJSON sources, data-driven styling, and interactive zoom-to-expand functionality.
Feature-state restyles a feature on hover without resending geometry — but it silently does nothing when features have no id. Here's the mechanism, a worked pattern, and the trade-offs.
Learn when to use Vector Tiles versus GeoJSON sources in Mapbox GL JS to maintain 60fps performance when visualizing high‑density geographic datasets.
