This example demonstrates how to construct a world map using D3.js, rendering individual countries as SVG paths with light green fills over a blue spherical background. The visualization loads geographic data from the world-atlas TopoJSON dataset and applies a geoAzimuthalEquidistant projection, clipped to a rectangular viewport using geoClipRectangle. It relies on d3.geoPath to generate the SVG paths and topojson.feature to convert the TopoJSON topology into GeoJSON features for display.
