{"version":"1.0","type":"rich","title":"World Population Map","description":"This visualization displays global population distribution using a natural Earth projection, with circle markers positioned at capital cities. Circle size encodes population magnitude, while color categorizes each country by continent. The visualization uses D3’s `geoNaturalEarth1` projection and `geoPath` for rendering country boundaries and graticules, with `topojson-client` converting TopoJSON world atlas data. Population and capital coordinates come from combined CSV datasets, with circle radii scaled proportionally to the square root of population.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2bd175f5e81d4e109310d81d2ad7a94f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
