This world map visualization displays global landmasses and country boundaries using a natural Earth projection. The map renders land areas in teal, country interiors in a lighter stroke, and graticules as thin gray lines over a light sphere background. Built with React and d3-geo, the visualization uses `geoNaturalEarth1`, `geoPath`, and `geoGraticule` to project and draw features. Geographic data comes from the world-atlas TopoJSON dataset, processed with `topojson.feature` and `topojson.mesh` for land polygons and country borders.
