This map depicts world landmasses and country borders using a Natural Earth projection. The visualization renders geographic features as SVG paths, with graticules and interior boundaries drawn as styled strokes. It loads GeoJSON and topology data from the World Atlas Topojson collection, processed with `feature` and `mesh`. The code builds paths using `geoNaturalEarth1`, `geoPath`, and `geoGraticule` from d3-geo, while React manages the component state and rendering. The sphere, landmasses, and borders are each styled distinctly to clarify spatial relationships.
