This example displays a world map with individual countries rendered as brown SVG paths outlined in light green, projected using the Natural Earth projection. It fetches geographic data from the world-atlas TopoJSON dataset and converts it to GeoJSON with topojson’s `feature` method. The visualization uses d3’s `geoPath` and `geoNaturalEarth1` to generate the map geometries, appending each country as a path element to a 980×495 SVG canvas.
