{"version":"1.0","type":"rich","title":"Fork of D3 world map example with TopoJSON to GeoJSON and circular indicators","description":"This map visualization displays Nobel Prize winners per country using a world map with circular indicators. Red circles, sized using `d3.scaleSqrt`, overlay each country's geographic centroid, and hovering highlights countries and shows a tooltip via SVG path interactions. The map renders through an equirectangular projection defined by `d3.geoEquirectangular` and `d3.geoPath`, converting TopoJSON data with the `topojson` library. Country data from a CSV file is joined with GeoJSON features to position each indicator.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1142861e80a944539387bf092e3e6d33?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
