{"version":"1.0","type":"rich","title":"Points on a Map","description":"A world map displays country boundaries and graticules, with hundreds of semi-transparent points marking city locations. The visualization uses D3’s `geoNaturalEarth1` projection and `geoPath` to render landmasses and interiors from World Atlas Topojson, while city coordinates are projected and drawn as SVG circles. React manages the component state, fetching data via `useEffect` and D3’s `csv` and `json` loaders.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1ca317655aec4c448dba17159a415e3f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
