Largest cities in the USA
This visualization displays the largest cities in the USA by 2020 population, with each city represented as a semi-transparent circle scaled by population size on a world map. The map includes land boundaries, country interiors, and graticules, all rendered as SVG paths using `d3.geoPath` with a `geoNaturalEarth1` projection. Cities are plotted by latitude and longitude coordinates using `d3.scaleSqrt` for circle radii. Data comes from a CSV of city populations, while country shapes use TopoJSON from World Atlas, with React managing the component state and D3 fetching the data.
