This example displays a world map with countries, graticules, and country borders rendered as SVG paths. The visualization uses a natural Earth projection defined by `d3.geoNaturalEarth1`, with `d3.geoPath` generating the geographic shapes. Landmasses appear in teal, graticules in gray, and country boundaries in a lighter teal. The data comes from the world-atlas TopoJSON file, processed through `topojson.feature` and `topojson.mesh` to extract land polygons and interior borders.
