This example displays a world map using a natural Earth projection, rendering countries as white shapes with dark blue outlines against a light blue ocean sphere. It loads geographic data from the world-atlas TopoJSON dataset via `d3.json`, converts it to GeoJSON with TopoJSON’s `feature` function, and draws paths using `d3.geoPath` and `d3.geoNaturalEarth1`. The visualization is built with D3 v5 and rendered as SVG elements.
