{"version":"1.0","type":"rich","title":"Affection Type Unknown Map","description":"This map of Chinese provinces visualizes the number of survey responses with an unknown affection type, using red circles sized by `d3.scaleSqrt` and positioned with `d3.geoCentroid` and the `d3.geoMercator` projection. Province borders are drawn as SVG paths from a TopoJSON file. Each circle’s radius encodes the `Unknown` column from a CSV dataset, joined to the map features via province ID. A square-root size scale maps values from 0 to 500 into radii between 0 and 20 pixels. The visualization uses `d3.geoPath` for rendering geographic features and includes a legend with circles and tick labels generated by a custom `sizeLengend` function.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7def7e5d96df462683c4a6067c2ead64?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
