This example shows an interactive world map with zoom and pan capabilities. Countries are rendered as styled SVG paths with hover highlighting, while the globe’s sphere is drawn as a separate background layer. The visualization uses `d3.geoNaturalEarth1` for projection, `d3.geoPath` to generate paths, and `d3.zoom` for interaction. Geographic data comes from the world-atlas TopoJSON file, processed via `topojson.feature`, and rendered as SVG with CSS-styled country shapes.
