This example displays a choropleth-style map of Mexico, rendered with a Mercator projection using d3.geoPath. The map shows state boundaries and graticules, with land areas filled in green and outlined in yellow, while graticules appear in blue and teal. The visualization is built with React, using d3.json to fetch TopoJSON data from a GitHub gist and topojson.feature to convert it into GeoJSON. The code is a fork of a Japan map example, adapted to focus on Mexico’s geographic layout.
