sites is not an array of google.maps.Markers

Similar questions:

One way to fix that is to create an array of google.maps.Marker objects in the setMarkers function and return it. Working code snippet:

var infowindow = null;
$(document).ready(function() {
  initialize();
});

function initialize() {

  var centerMap = new google.maps.LatLng(95.32, 14.82);

  var myOptions = {
    zoom: 0,
    center: centerMap,
    mapTypeId: google.maps.MapTypeId.HYBRID
  };

  var map = new google.maps.Map(document.getElementById("map_radius_canvas"), myOptions);



  var gmarkers = setMarkers(map, sites);
  var markerCluster = new MarkerClusterer(map, gmarkers);
  infowindow = new google.maps.InfoWindow({
    content: "loading..."
  });

  var LatLngList = new Array(
    new google.maps.LatLng(11.0168445, 76.9558321), new google.maps.LatLng(11.0168445, 76.9558321), new google.maps.LatLng(11.0168445, 76.9558321), new google.maps.LatLng(11.0168445, 76.9558321), new google.maps.LatLng(-3.7318616, -38.5266704), new google.maps.LatLng(21.3967, -157.8994), new google.maps.LatLng(45.4278901, -75.6958523), new google.maps.LatLng(26.8465108, 80.9466832), new google.maps.LatLng(30.9602, -85.1639), new google.maps.LatLng(33.9737, -87.0043));

  var bounds = new google.maps.LatLngBounds();
  for (var i = 0, LtLgLen = LatLngList.length; i < LtLgLen; i++) {
    bounds.extend(LatLngList[i]);
  }

  map.fitBounds(bounds);

  var bikeLayer = new google.maps.BicyclingLayer();
  bikeLayer.setMap(map);
}
