mapboxMapbox GeoJSON clustering: enable it or render every point?
Decide when to enable native GeoJSON clustering in Mapbox GL JS, how to style clusters, and how to validate click and performance behavior.
Mapbox Point Clustering: A Source Option, Not a Layer Trick
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.
Client-Side Clustering in Mapbox GL JS: When the Browser Should Do the Aggregation
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.
Add a Custom GeoJSON Layer with Data‑Driven Circle Styling in Mapbox GL JS
Step‑by‑step guide to load a GeoJSON point set into Mapbox GL JS and style circle radii dynamically using a data‑driven expression.
Using Mapbox GL JS client-side clustering for large GeoJSON point sets
Learn how to enable client-side clustering in Mapbox GL JS to render thousands of points efficiently, with a code example and performance considerations.
Implementing Client-Side Point Clustering in Mapbox GL JS
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.
Mapbox feature-state: hover highlighting without reloading your data
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.
