This visualization displays a world map with country boundaries rendered as filled teal shapes against a light gray sphere, overlaid with graticule lines and interior borders. The map uses `d3.geoNaturalEarth1` for projection and `d3.geoPath` to draw the geographic features from World Atlas TopoJSON data loaded via `d3.json`. React manages the component structure, while SVG elements render the map within a fixed 960×500 viewport. Styling applies a polished color palette with subtle stroke distinctions for graticules and coastline interiors.
