This visualization displays a zoomable, natural Earth projection map with countries colored light green. Users can pan and zoom the map using the d3.zoom behavior, which applies a transform to the SVG group containing all geographic paths. The map data comes from the world-atlas TopoJSON files, with country names joined from TSV data. Hovering over any country turns it red, implemented through CSS :hover rules. The visualization uses d3.geoPath, d3.geoNaturalEarth1, and the topojson.feature API to render the geographic features.
