This visualization displays a world map with countries colored light green on a blue sphere, using D3 v5 and topojson. It shows geographic boundaries and continent information from the World Atlas dataset. The map supports zooming and panning through D3’s zoom and event APIs. Hovering a country triggers a CSS hover effect turning it red and displaying a tooltip with the country name and continent, built using d3.geoPath and d3.geoNaturalEarth1 projections.
