This example shows an interactive world map that supports zooming, with countries colored white on a blue sphere and highlighted in red on hover. The map displays country names as tooltips sourced from a TSV file. It builds the map using d3.geoPath with a d3.geoNaturalEarth1 projection, and enables zoom behavior through d3.zoom. The map renders as SVG paths generated from TopoJSON world data via the topojson library, with interaction managed through the zoom event handler.
