{"version":"1.0","type":"rich","title":"Circles on a map","description":"This visualization displays global population data for 2018 using circles overlaid on a natural Earth projection map. The circles, sized with a square root scale, represent population magnitudes, while a legend explains the scaling. A color legend and interactive zooming are also included. The code uses D3 v5 APIs like `geoPath`, `geoNaturalEarth1`, `scaleSqrt`, and `topojson.feature`, with data loaded from a CSV file and a TopoJSON world atlas. The visualization is rendered as an SVG within a React framework.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1da179d973374c38827a2ec5c7839e27?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
