Google Maps v3 でデフォルトの拡大率を指定する方法を教えてください。次のサンプルを参考にGoogle mapを実装しましたが、コード中のどこにどのようにデフォルトの拡大率を指定すればよいかわかりません。 http://japonyol.net/editor/v3metro.html どうぞご教授お願いいたします。

こんな感じ。

    var myOptions = {
            mapTypeId: google.maps.MapTypeId.ROADMAP,
            zoom: 5     /* ★コレ！ */
        };
    map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);

API のリファレンスを見るべし。
