This example presents a world map using the Natural Earth projection, rendered as an SVG with D3.js. Countries are drawn as paths using `d3.geoPath` and a `geoNaturalEarth1` projection, with a distinct sphere path representing the globe. The map is interactive, allowing users to zoom and pan via the `d3.zoom` API. Geographic data is loaded from a remote JSON file containing TopoJSON, which is converted to GeoJSON features using the `topojson` library. The visualization employs a brown background and a dark green sphere fill, with countries styled in a light beige.
