This world map visualization displays country borders as green polygons on a steel-blue background, rendered using SVG. It uses d3’s `geoNaturalEarth1` projection and `geoPath` to draw the sphere and countries, with geographic data loaded from the world-atlas TopoJSON file via `json()` and parsed with `feature()`. Each country is appended as a path element with a black stroke, creating a simple, static choropleth-free view of global landmasses.
