This example displays a world map with city points overlaid, using a Natural Earth projection via d3.geoNaturalEarth1 and d3.geoPath. The map includes land boundaries, graticules, and interiors rendered as SVG paths from World Atlas TopoJSON data. City locations, loaded from a CSV with d3.csv, are plotted as semi-transparent circles. The visualization is built with React and D3 v5, demonstrating a clean, styled cartographic composition with an equirectangular-like aesthetic.
