This example presents a polished world map using a Natural Earth projection, displaying country boundaries and graticules. It visualizes geographic data from the World Atlas TopoJSON dataset, with land masses filled in teal and country borders drawn as interior mesh lines. The visualization uses React for component structure and d3-geo APIs including `geoNaturalEarth1`, `geoPath`, and `geoGraticule` to project and render the map. The topojson library converts the TopoJSON topology into GeoJSON features and computes the interior boundaries between countries, with all elements rendered as SVG paths.
