This interactive world map visualizes country boundaries using an equirectangular projection, with countries rendered as light green SVG paths and a sky-blue sphere background. Viewers can zoom and pan the map using D3's zoom behavior. The visualization loads TopoJSON data from the world-atlas package, converts it to GeoJSON using `topojson.feature`, and renders paths with `d3.geoPath`. Hovering over a country triggers a CSS color change to maroon, providing basic interactivity. The implementation uses D3 v5 with ES6 module imports for `json`, `geoEquirectangular`, and `zoom`.
