Could you have any ideas why my geojson file doesn't display? here is the code I have.
<script> function makeSomeMaps() { map = d3.carto.map(); d3.select("#map").call(map); countryLayer = d3.carto.layer.geojson(); countryLayer.path("nairobiwardsformat2.geojson") .label("Wards") .renderMode("svg") .cssClass("country") .clickableFeatures(false); map.addCartoLayer(countryLayer); map.setScale(2); } </script>
