            var pinColor = "FE7569";
            var pinImage = new google.maps.MarkerImage("http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=%E2%80%A2|" + pinColor,
            new google.maps.Size(21, 34),
            new google.maps.Point(0,0),
            new google.maps.Point(10, 34));
            var pinShadow = new google.maps.MarkerImage("http://chart.apis.google.com/chart?chst=d_map_pin_shadow",
            new google.maps.Size(40, 37),
            new google.maps.Point(0, 0),
            new google.maps.Point(12, 35));
            var data = google.visualization.arrayToDataTable(dataArray);
            var map = new google.visualization.Map(document.getElementById('map_div'));
            map.Marker({
                position: new google.maps.LatLng(0,0), 
                map: map,
                icon: pinImage,
                shadow: pinShadow
            });
            var options = {mapType: 'terrain',showTip: true,useMapTypeControl:true};

            map.draw(data,options);
