Estou tentando implementar o Google maps no jsFiddle para fazer outra pergunta, mas não consigo ver o mapa:http://jsfiddle.net/hashie5/aknYP/

Eu adicionei o script gmap nos recursos

Como posso mostrar o mapa no jsFiddle?

function initialize() {
var myLatlng = new google.maps.LatLng(50.965049,5.484231);
var myOptions = {
  zoom: 14,
  center: myLatlng,
  mapTypeId: google.maps.MapTypeId.ROADMAP
}

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

var contentString = 
    '<div id="infowindow">' +
    'Galaconcert<br />' +
    'Jaarbeurslaan 2-6<br />' +
    '3690 Genk' +
    '</div>'
;

var infowindow = new google.maps.InfoWindow();

var marker = new google.maps.Marker({
    position: myLatlng,
    map: map,
    title: 'Galaconcert'
});
google.maps.event.addListener(marker, 'click', function() {
    infowindow.setContent(contentString);
    infowindow.open(map, marker);
});
}
