This example displays a world map rendered as dark green countries with black outlines on a light blue background. The visualization uses an SVG canvas and relies on the Natural Earth projection via `geoNaturalEarth1` to convert geographic coordinates into planar paths. Data is loaded asynchronously from the world-atlas TopoJSON file on jsDelivr, with country features extracted using TopoJSON’s `feature` function. The paths are generated and appended using `d3.geoPath` and `selectAll`, demonstrating a straightforward choropleth-style mapping without additional interactivity or styling variations.
