Fork of world map w/ cities & countries pop!
A world map visualization displays global city populations and country population data, with city circles sized by population and country polygons colored by opacity according to population. The visualization uses a Natural Earth projection from d3-geo-projection, rendered with React and SVG paths via d3.geoPath. City data comes from the Simplemaps World Cities Database, while country boundaries use World Atlas TopoJSON. Hovering over cities or countries reveals population tooltips, with graticules and geographic reference lines overlaid for context.
