{"version":"1.0","type":"rich","title":"Points on a Map","description":"This example displays a world map with small, semi-transparent dots marking cities with populations over 50,000. The map is rendered as SVG using D3’s `geoNaturalEarth1` projection, with landmasses, graticules, and country interiors drawn via `geoPath`. City locations are projected from latitude and longitude coordinates loaded from a CSV file, with each point drawn as a circle. The React application uses custom hooks to fetch the world atlas and city data, with styling applied through CSS classes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4a25c228e01141d38738ba8424c3d2d5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
