// - The file must either be on the same domain as the page that requests it,
//   or both the server it is requested from and the user's browser must
//   support CORS.
var runLayer = omnivore.kml('/mapbox.js/assets/data/line.kml')
    .on('ready', function() {
        map.fitBounds(runLayer.getBounds());

        // After the 'ready' event fires, the GeoJSON contents are accessible
        // and you can iterate through layers to bind custom popups.
        runLayer.eachLayer(function(layer) {
            // See the `.bindPopup` documentation for full details. This
            // dataset has a property called `name`: your dataset might not,
            // so inspect it and customize to taste.
            layer.bindPopup(layer.feature.properties.name);
        });

to create your own custom map and use it in this example.
Use this example by copying its source into your own HTML page and replacing the Map ID with one of your own from your projects. Having trouble with JavaScript? Try out Codecademy or contact our support team.
