{"version":"1.0","type":"rich","title":"Points on a Map","description":"A world map displays the locations of cities with populations over 50,000 as small semi-transparent dots, overlaid on landmasses with country borders and graticules. Using React, the visualization loads GeoJSON world-atlas topology and city data via D3’s `json` and `csv` methods, then projects coordinates with `geoNaturalEarth1` and renders SVG paths and circles through `geoPath`. The map’s gray land, interiors, and sphere are styled distinctly, while city points use D3’s `projection` to convert longitude and latitude into screen positions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c041e6fd930e4b95977ca0a72f455ed6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
