This visualization displays a world map rendered as an SVG, with country boundaries drawn from TopoJSON data sourced from the world-atlas dataset. It uses D3 v5’s `d3.geoPath` and `d3.geoEquirectangular` to project and draw each country as a blue path with white strokes, while a white sphere outlines the globe. The `topojson.feature` method converts the TopoJSON topology into GeoJSON features for rendering. Hovering over any country changes its fill color to orange via CSS.
