Map Cluster

Algorytmus to create clusters on maps.

Handling

PHP

$markers = [
    [ "latLng" => [ "lat" => "24.794044", "lng" => "16.988475" ], ... ],
    ...
];

$ClusterAndMarker = cluster($markers);

var_dump($ClusterAndMarker);

[
    "cluster" => [
        [
            "latLng" => [ "lat" => "1.123456", "lng" => "1.123456" ],
            "count" => X
        ],
        ...
    ],
    "marker" => [
        [ /* you marker object */ ],
        [ /* you marker object */ ],
        ...
    ]
]

JavaScript

let markers = [
    { latLng : { lat : "24.794044", lng : "16.988475" }, ... },
    ...
];

let ClusterAndMarker = cluster(markers);

console.log(ClusterAndMarker);

[
    cluster : [
        {
            latLng : { lat : "1.123456", lng : "1.123456" },
            count : X
        },
        ...
    ],
    marker : [
        { /* you marker object */ },
        { /* you marker object */ },
        ...
    ]
]

latLng Object

If you have a different coordinate structure, you can adjust the script.
