This example renders a world map using a Natural Earth projection, highlighting countries as solid yellow shapes against a blue ocean sphere. The visualization builds the map with D3’s `geoPath` and `geoNaturalEarth1` projection, while the TopoJSON `feature` function converts country boundaries from a JSON dataset. Path elements are generated for each country, with styling controlled by CSS classes for the sphere and landmasses. The map is drawn using SVG, and the data source is the world-atlas countries-110m JSON file.
