{"version":"1.0","type":"rich","title":"Points on a Map","description":"This example visualizes global population data by plotting cities as semi-transparent circles on a Natural Earth projected world map. A square-root scale maps each city’s population to circle radius, with the largest cities appearing most prominent. The visualization uses React for component structure and D3 v5 APIs including `geoNaturalEarth1`, `geoPath`, `geoGraticule`, and `scaleSqrt`. Country boundaries and graticules come from the World Atlas TopoJSON, while city coordinates and populations are loaded from a clean CSV dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/07482872454145d6a449136e3abee272?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
