This example displays a world map showing country boundaries and land masses, with a focus on geographic layout rather than quantitative data. The map renders an equal Earth projection using `d3.geoEqualEarth`, with graticule lines and a styled sphere background. Country polygons are drawn via `d3.geoPath`, while interior borders are generated from TopoJSON mesh data loaded from the world-atlas dataset. The visualization uses React for component structure and SVG for rendering, with CSS controlling the color scheme for countries, borders, and the surrounding ocean.
