This map displays world country boundaries in an interactive natural Earth projection. It uses D3's `geoNaturalEarth1` projection and `geoPath` to render SVG paths, with a topojson `feature` transformation applied to country data from a world-atlas JSON file. The visualization includes a sphere background and country shapes in distinct colors. Zooming is enabled through D3's `zoom` event, which updates the group element's transform based on the current view.
