This example presents an interactive world map rendered in SVG using D3.js. It displays country boundaries as light green shapes with a blue sphere background, using the d3.geoNaturalEarth1 projection. Users can pan and zoom the map through the d3.zoom API, which applies transforms to the grouped SVG elements. Country data comes from the world-atlas TopoJSON and TSV files, with country names added as tooltips via the title element, and hover states change the fill color to red.
