The map below shows the city boundaries for the state in the United States. In FF and Safari, city boundaries are displayed correctly, but in Google Chrome, many boundary arcs are connected to the wrong nodes. My code follows an excellent tutorial here . The essence of my code, which displays the internal boundaries, is the culprit, and I tried to sort the functions of the topology, but this did not affect. Here is a snippet:
svg.append("path") .datum(topojson.mesh(maine, maine.objects.subunits, function(a, b) { return a !== b })) .attr("d", path) .attr("class", "subunit-boundary interior");
