This visualization presents a world map using the spherical Mercator projection. Landmasses are rendered in a deep red, with graticules shown in light gray and country interiors outlined in teal against a pale sphere. The example leverages d3.geoPath, geoMercator, and geoGraticule from D3 to generate geographic shapes, while React manages the SVG rendering. Topological data from World Atlas 110m is processed with topojson’s feature and mesh functions to distinguish land from country interiors. The projection and custom styling convey a clean, minimalist cartographic aesthetic.
