This example renders a choropleth-style map of Mexico’s states using a Mercator projection implemented with `d3.geoMercator` and `d3.geoPath`. The SVG marks are drawn from TopoJSON data loaded via `d3.json` and converted with `topojson.feature`, with graticules displayed as background paths. Built as a React component, the visualization fetches state boundaries from a public gist of arcgis.com data, processed with mapshaper. The current center coordinates are set, but the README notes the map still needs alignment on the rendered image.
