GMaps.js — Marker Clusterer

With GMaps.js you can use a marker clusterer to group large amount of markers:

map = new GMaps({
  div: '#map',
  lat: -12.043333,
  lng: -77.028333,
  markerClusterer: function(map) {
    return new MarkerClusterer(map);

You can use MarkerClusterer or MarkerClustererPlus. If you want to use a custom marker clustering library, you have to define a addMarker method.
