This fork of a simple world map displays all countries as solid green shapes on a light blue background, projected using the Natural Earth projection. It fetches geographic data from the world-atlas TopoJSON file and converts it into GeoJSON features using the `feature` function from TopoJSON. The map is rendered as SVG paths via `d3.geoPath` with a `geoNaturalEarth1` projection, where each country is appended as a path with the class "country". The visualization uses D3 v5 to load the dataset and generate the static map.
