This visualization shows the locations of cities worldwide as small dots overlaid on a Natural Earth projection map, with country boundaries rendered in light gray. The map is drawn using d3-geo’s geoNaturalEarth1 projection and geoPath, while city coordinates from a reduced World Cities CSV are projected and plotted as circles. Graticule lines and an outline frame the globe. Data loading uses fetch, topojson-client for country features, and d3.csvParse for city entries, with asynchronous state management coordinating the rendering.
