This example presents a stylized world map, rendered with country boundaries sourced from the World Atlas TopoJSON. The visualization showcases the Earth's landmasses and graticules using a Natural Earth projection. The code employs `d3.geoNaturalEarth1`, `d3.geoPath`, and `d3.geoGraticule` to project the geographic data into SVG paths within a React application. The map is composed of distinct layers, including a light gray sphere, black landmasses, teal interiors, and subtle graticule lines, creating a refined visual aesthetic.
