This map renders world countries as green vector shapes on a dark blue sphere, using D3's `geoNaturalEarth1` projection and `geoPath` to generate the SVG paths. The map imports country boundaries from the `world-atlas` dataset and supports zooming via the `zoom` API, which updates the group transform on zoom events. Hovering over a country triggers a CSS `:hover` rule, turning the shape red and displaying its name via a `title` tooltip.
