    container: 'map', // container id
    style: MapStyle.STREETS, 
    center: [-122.42162, 37.78106], // starting position
    zoom: 12.69 // starting zoom
});

    document.getElementById('info').innerHTML =
        // e.point is the x, y coordinates of the mousemove event relative
        // to the top-left corner of the map
        JSON.stringify(e.point) +
        '<br />' +
