This example displays a simple world map with countries and a sky-blue sphere background. It uses the D3.js library, specifically `d3.geoNaturalEarth1` for the projection and `d3.geoPath` to generate SVG paths for the country outlines. The map loads geographic data from the world-atlas TopoJSON dataset via `d3.json` and converts it with the `topojson.feature` API. Countries are rendered as pink shapes with a thin blue stroke, providing a clear, minimal visualization of global landmasses.
