This example displays a Natural Earth projection world map using SVG paths. Countries are rendered in blue with white borders, set against a light blue ocean sphere and graticule grid. The code uses D3 v7’s `d3.geoNaturalEarth1` projection, `d3.geoPath`, and `d3.geoGraticule` to draw geographic features. It loads `world-atlas` TopoJSON data, converts it to GeoJSON via `topojson.feature`, and binds the resulting country features to path elements.
