This example displays a world map using a natural Earth projection, with countries rendered as green vector paths against a blue sphere and background. The visualization loads geographic data from the world-atlas TopoJSON dataset and converts it to GeoJSON features using the topojson feature function. D3’s geoPath and geoNaturalEarth1 handle the projection and path generation, while the country paths are styled with CSS and include a hover effect that changes their fill color. The map is rendered entirely as SVG.
