This visualization depicts a orthographic projection of the world map, rendered as a solid sphere with graticule lines and individual country landmasses. The `d3.geoOrthographic` projection and `d3.geoPath` generate the sphere and land shapes from TopoJSON data sourced from the world-atlas package. Country interiors are outlined using a topological mesh, while styled SVG paths in React manage the visual hierarchy, using fill and stroke colors to distinguish land, graticules, and the surrounding sphere.
