{"version":"1.0","type":"rich","title":"Fork of Affection Type Unknown Map","description":"This map of China displays the number of unknown-affection cases per province, with red circles sized proportionally to the count and provinces colored by category. The visualization uses a Mercator projection with `d3.geoPath` to render province boundaries, and `d3.scaleSqrt` to map case counts to circle radii via `d3.geoCentroid`. A legend, generated by a custom `sizeLengend` function, explains the circle sizes, while data comes from a CSV file merged with TopoJSON-provided province geometries. The map also supports hover highlighting through CSS, and code loads data asynchronously using `Promise.all` with `d3.csv` and `d3.json`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f52b09ef8f8c40eb988c34abb7660599?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
