This example shows a world map rendered with a Natural Earth projection, displaying country boundaries as light green polygons against a blue sphere. The visualization uses D3.js v5 and TopoJSON to load and convert world-atlas geodata, with `d3.geoNaturalEarth1` and `d3.geoPath` generating the SVG paths. It draws the sphere background and country outlines via appended `<path>` elements, relying on the `feature` method to extract country shapes from TopoJSON.
