This example renders a world map using D3.js version 5 and TopoJSON, displaying countries as light green paths with subtle black strokes against a blue spherical backdrop. It uses `d3.geoNaturalEarth1` for the projection and `d3.geoPath` to generate SVG paths from geographic features. The map loads country boundaries from the world-atlas TopoJSON dataset (110m resolution) via `d3.json`, then appends each country path to the SVG canvas. The visualization demonstrates a clean, static cartographic rendering suitable for introductory mapping tutorials.
