This visualization displays a world map using a natural Earth projection, with countries rendered in red against an orange sphere. The map is drawn as SVG paths using `d3.geoNaturalEarth1` and `d3.geoPath`, with geographic data loaded from a TopoJSON file hosted on GitHub. The code imports `feature` from `topojson` to convert the TopoJSON topology into GeoJSON features, then appends each country path to the SVG. Styling is defined in a separate CSS file, outlining countries with black strokes.
