This world map uses a natural Earth projection to display global country boundaries, with the sphere rendered in green and landmasses in a dark tan with subtle black strokes. The visualization is built with D3 version 5 and topojson, using `d3.geoPath` and `d3.geoNaturalEarth1` to project and draw the map. Country features are loaded from a remote JSON source that contains coordinate data for each nation.
