A choropleth-style SVG map of Mexico renders geographic region boundaries using D3's `geoMercator` projection and `geoPath`. The map displays each state as a green path with yellow strokes, overlaid with blue graticule lines. Geographic data loads from a TopoJSON file via D3's `json` function and `topojson.feature`, while React manages the component state. The visualization also imports multiple alternative projections (`geoEqualEarth`, `geoNaturalEarth1`) though only Mercator is applied.
