This visualization displays a world map using an equirectangular projection, with countries rendered in light green and an indigo stroke atop a sky-blue sphere. It shows geographic boundaries from the World Atlas TopoJSON dataset, rendered as SVG paths via d3.geoPath. The map supports interactive pan and zoom, implemented with d3.zoom, and country paths change to maroon on hover through CSS styling. The code uses d3.json to load the data and topojson.feature to convert it to GeoJSON.
