        coordinates: [-73.9840, 40.7271]
    },
    properties: {
        title: 'Hello world!',
        'marker-color': '#f86767'
    }
}).addTo(map);

// Iterate over the featureLayer we've called "marker"
// and open its popup instead of clicking to trigger it.
marker.eachLayer(function(m) {
  m.openPopup();
});
