A world map rendered in SVG displays city points overlaid on landmasses and graticules. The visualization uses d3.geoNaturalEarth1 for projection and d3.geoPath to draw geographic features from World Atlas TopoJSON data. Each city is plotted as a semi-transparent circle positioned via the projection function. City coordinates come from a CSV dataset loaded with d3.csv, while topography is handled with topojson.feature and topojson.mesh.
