Here is the code I wrote in View file

<head>
	<? 
	$map = $app->library->gmap;
	$map->printGoogleJS(); 
	$map->setMapType("satellite");
	?>
</head>
<body>
	<?
	$map->addGeoPoint(23.700001,90.389999,"Dhaka");
	$map->showMap();
	?>
</body>

And added a google map API key in app/config/configs.php as

	$configs['google_map_api']="api key";

And you can see the live demo of this one at http://javapark.net/hasin/orchid/gmaps
