This example presents a world map using the natural Earth projection. Countries are rendered as green filled paths from a world-atlas GeoJSON dataset, while the sphere background is light blue. The visualization uses d3.geoNaturalEarth1 for projection and d3.geoPath to convert geometry into SVG paths, with the topojson library’s feature function to extract country features. The map is styled with CSS classes, including semi-transparent gray country borders.
