This example renders a world map using D3.js and TopoJSON, displaying countries as light green shapes against a dark blue spherical background. It uses d3.geoNaturalEarth1 for the projection and d3.geoPath to generate SVG paths from the world-atlas dataset. The code loads TopoJSON data, converts it to GeoJSON with topojson.feature, and appends country paths to an SVG container. The visualization demonstrates basic data binding and DOM manipulation while showing geographic features with minimal styling.
