07 · Clusters

5,000 random points indexed by the zero-dep GeoJSONClusterSource. Pan and zoom to re-query — the index pre-builds one KD-tree per zoom level, so getClusters is O(log N).

Full source: 07-clusters.ts

const source = new GeoJSONClusterSource({ radius: 50, maxZoom: 16 })
source.load(features)
const items = source.getClusters([west, south, east, north], zoom)
