This visualization shows a world map where individual countries appear in light green against a blue ocean sphere, with hover interactions highlighting each country in red. Built with D3 v6 and TopoJSON, it uses a natural Earth projection to render geographic features from the World Atlas countries dataset. The map supports pan and zoom through D3’s zoom behavior, which applies SVG transforms to the grouped country paths. Tooltips display country names via SVG title elements, while CSS hover rules trigger the color change.
