This choropleth map displays New York state’s cities and towns as red, semi-transparent polygons with black borders, rendered on a whitesmoke background using SVG. It uses `d3.json` to load TopoJSON data from a gist, converts it to GeoJSON with `topojson.feature`, and draws the map with `d3.geoPath`. The map is static, with no interactions, scales, or projections specified, and only includes a minimal styling for the county class.
