This visualization renders a world map using the Natural Earth projection, displaying countries as light green polygons against a blue ocean sphere. The code loads GeoJSON data from the World Atlas TopoJSON file (110m resolution), converts it using the `feature` method from topojson, and draws the paths with `d3.geoPath` and `geoNaturalEarth1`. It demonstrates the classic D3 pattern of fetching external geospatial data, projecting it, and appending SVG paths to the canvas.
