This example uses D3.js to render an interactive world map from TopoJSON and TSV data loaded from the world-atlas package. Countries are drawn as SVG paths using the d3.geoNaturalEarth1 projection and d3.geoPath, with hover effects changing their fill color. The visualization incorporates d3.zoom to enable pan and zoom transformations on the map group, while a sphere background is rendered from a GeoJSON Sphere object. Country names are joined to features via ISO numeric codes and displayed as SVG title tooltips.
