{"version":"1.0","type":"rich","title":"Points on a Map","description":"This example displays city locations as semi-transparent teal dots on a natural Earth projection world map, highlighting urban centers with populations exceeding 50,000. The visualization uses React for component structure and D3 v5’s `geoNaturalEarth1` projection with `geoPath` to render land masses, country boundaries, graticules, and a sphere outline. City coordinates from the Simplemaps World Cities Database are projected using `projection([d.lng, d.lat])` into SVG circles. The map background and land fill are styled via CSS, with graticules providing geographic reference lines.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8a7e4ebedbb040588e6f51a25d42259e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
