This example shows a world map rendered as a simple SVG visualization. It draws a blue sphere as the globe backdrop and then overlays individual country paths in light green with thin black strokes. The map uses a natural Earth projection and loads geographic data from the World Atlas TopoJSON dataset. The code employs `d3.geoPath` with `d3.geoNaturalEarth1` for projection, and uses `topojson.feature` to convert TopoJSON country boundaries into GeoJSON for rendering. All map elements are drawn as SVG paths inside a 960×500 viewport.
