This example displays a world map rendered as dark green countries with dark grey outlines on an aqua background. It uses the D3 library, specifically `d3.geoNaturalEarth1` and `d3.geoPath`, to project and draw geographic shapes from the world-atlas dataset’s countries-110m JSON. The code fetches that data, extracts country features using topojson, and appends SVG paths to the canvas, resulting in a static chloropleth-style map.
