This example displays a world map rendered as an SVG using React and D3 v5. It loads geographic data from the world-atlas TopoJSON dataset and converts country boundaries into GeoJSON features with `topojson.feature`. The map is drawn as a collection of black path elements, one per country, using a line generator with natural curve interpolation. The visualization focuses on geopolitical outlines rather than thematic data, presenting a minimal, clean cartographic view.
