// Note that calling `.eachLayer` here depends on setting GeoJSON _directly_
// above. If you're loading GeoJSON asynchronously, like from CSV or from a file,
// you will need to do this within a `featureLayer.on('ready'` event.
featureLayer.eachLayer(function(layer) {

    // here you call `bindPopup` with a string of HTML you create - the feature
    // properties declared above are available under `layer.feature.properties`
    var content = '<h2>A ferry ride!<\/h2>' +
        '<p>From: ' + layer.feature.properties.from + '<br \/>' +
        'to: ' + layer.feature.properties.to + '<\/p>';
    layer.bindPopup(content);
