This map of the world highlights countries in light green against a blue sphere, with each country displaying its name as a tooltip on hover. It uses d3.geoPath with a geoNaturalEarth1 projection to generate SVG paths for the landmasses, and d3.zoom to enable interactive panning and zooming. Country names come from the world-atlas TSV file, while the geographic boundaries come from the corresponding TopoJSON file processed via the topojson library’s feature function.
