<script src="https://unpkg.com/supercluster@2.2.0/dist/supercluster.min.js"></script>

var index = supercluster({
    radius: 40,
    maxZoom: 16
});
index.load(points);
index.getClusters([-180, -85, 180, 85], 2);

Clustering 6 million points in Leaflet:

Methods

• load(points) : this

Loads an array of GeoJSON.Feature objects. Each feature's geometry must be a GeoJSON.Point. Once loaded, index is immutable.

• getClusters(bbox, zoom) : Array[GeoJSON.Feature](http://geojson.org/geojson-spec.html#feature-objects)

For the given bbox array ([westLng, southLat, eastLng, northLat]) and integer zoom, returns an array of clusters as GeoJSON.Feature objects.
