API

let clusters: ICluster = new Geocluster(coordinates[, zoom]).clusters;

coordinates is an Array of ICoordinate { latitude: number; longitude: number; }.

zoom value from 1 to 20.

clusters is an Array of cluster objects ICluster, which have centroid and elements properties.

Sample Code

import { ICoordinate, ICluster, Geocluster } from "geo-cluster";

let zoom = 2;

let coordinates: ICoordinate = [
    {
        latitude: 10,
        longitude: 20
    },
    {
        latitude: 20,
        longitude: 20
    },
    {
        latitude: 10,
        longitude: 30
    },
    {
        latitude: 40,
        longitude: 20
    }
];

let clusters: ICluster = new Geocluster(coordinates, zoom).clusters;
