7:         ];  
8:   var mapProp = {  
9:      center:new google.maps.LatLng(-33.890542, 151.274856),  
10:      zoom:5  
11:      };  
12:   var map=new google.maps.Map(document.getElementById('MAP_CANVAS') //fill with your id  
13:      ,mapProp);  
14:  //Loop markers  
15:   for (var i = 0; i < markerArr.length; i++) {  
16:    var dot = markerArr[i];  
17:    var myLatLng = new google.maps.LatLng(dot[1],dot[2]);  
18:    var infowindow = new google.maps.InfoWindow({  
19:     }); //Just create InfoWindow Object  
20:     var marker = new google.maps.Marker({  
21:       position: myLatLng,  
22:       map: map,  
23:       title: dot[3],  
24:      html : dot[0] // info window content,  
25:     });  
26:     google.maps.event.addListener(marker, 'click', function() {  
27:      infowindow.setContent(this.html); //yeah got its content  
28:       infowindow.open(map,this);
