{"version":"1.0","type":"rich","title":"Circles on a map","description":"This map visualization displays circles sized by a country’s 2018 value, positioned at each country’s centroid using the `geoNaturalEarth1` projection and `geoPath` for rendering the world in SVG. The circles’ radii come from `scaleSqrt`, while countries are colored green or red based on whether they have a value, with a categorical `scaleOrdinal` color legend. Data is loaded from a CSV and TopoJSON via `d3.csv` and `d3.json`, processed with `topojson.feature`, and the SVG supports zooming through `d3.zoom`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/787502fcb7334a4c8c3d3c9bd218800d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
