This example demonstrates how to create a world map using D3.js, rendering continents as light green polygons on a blue sphere. It uses the `d3.geoNaturalEarth1` projection and `d3.geoPath` to generate SVG paths from TopoJSON data loaded from the world-atlas package via `d3.json`. The code also draws a background sphere path and applies stroke styling to country boundaries. All visual elements are rendered as SVG in a single 960×500 viewport.
