This example shows a world map with countries drawn as light green shapes outlined in orange on a light blue background. It uses D3.js to fetch geographic data from the `world-atlas` countries-110m.json file and the TopoJSON `feature` function to process it. The map is rendered into an SVG using the `d3.geoPath` and `d3.geoNaturalEarth1` projection, with country boundaries generated from the dataset's geometric features.
