This example displays an interactive world map rendered with SVG, using a natural Earth projection. Countries are colored light green and turn red on hover, with a blue sphere as the background. The visualization uses `d3.geoPath` and `d3.geoNaturalEarth1` to generate the map from TopoJSON and TSV data provided by the world-atlas package. A `d3.zoom` handler enables panning and zooming the entire map group.
