Fork of Let's make a map with D3.js!
This example renders a world map using a natural Earth projection, displaying country boundaries as colored paths over a blue spherical backdrop. It loads geographic data from the world-atlas TopoJSON dataset and converts it to GeoJSON using the topojson `feature` method. The map is drawn with D3 v5’s `geoPath` and `geoNaturalEarth1` projection, while each country is styled as a light green filled SVG path with a subtle black stroke. The visualization demonstrates a straightforward, static cartographic rendering with minimal interactive or animated elements.
