{"version":"1.0","type":"rich","title":"Mapping : Part 2 - Cities","description":"This example visualizes worldwide cities as semi-transparent teal dots layered over a natural Earth projection map. It uses d3.geoNaturalEarth1 and d3.geoPath to render landmasses, graticules, and interior boundaries from the world-atlas TopoJSON dataset, while city coordinates are plotted via d3.csv from a cleaned world cities dataset. The React component fetches both data sources asynchronously using useEffect, then projects each city’s longitude and latitude into SVG circles with fixed pixel radii.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fdcc3bb814d04c3da989ef1926000837?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
