  .addLayer(L.mapbox.styleLayer('mapbox://styles/mapbox/streets-v11'));

// Omnivore will AJAX-request this file behind the scenes and parse it:
// note that there are considerations:
// - The CSV file must contain latitude and longitude values, in column
//   named roughly latitude and longitude
// - 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.
omnivore.csv('/mapbox.js/assets/data/airports.csv').addTo(map);
