I am trying to load map markers dynamically with leaflet and am getting this error:

Uncaught Error: Invalid LatLng object: (NaN, NaN)

I am using this javascript to load my markers:

            var lat;

            var lng;





            for (i = 0; i < data.length; i++) {

                lat = parseFloat(data[i].lat);

                lng = parseFloat(data[i].lng);



                L.marker([lat, lng]).addTo(map);

            }

My json I am reading is this:
