{"version":"1.0","type":"rich","title":"Dataviz 10 - Points on map","description":"This visualization displays a world map with points marking cities that have populations exceeding 50,000, using data from the Simplemaps World Cities Database. The map is rendered with SVG paths generated by `d3.geoPath` and a `geoNaturalEarth1` projection, featuring graticules, land masses, and interior boundaries from the World Atlas TopoJSON. City locations are plotted as semi-transparent teal circles positioned via the projection function. The visualization is built with React and D3 v5, loading geographic and city datasets asynchronously through custom hooks before rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/99b84f5df108473e823791705ad12162?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
