{"version":"1.0","type":"rich","title":"Affection Type Unknown Map","description":"This map of China visualizes provincial data on affection types, specifically highlighting the \"Unknown\" category through red circles positioned at each province’s centroid. The map uses an SVG rendering with a Mercator projection and loads geographic boundaries from a TopoJSON file while joining CSV data by province ID. Circle radii are scaled using `d3.scaleSqrt` based on unknown values, with a custom size legend showing tick values. Provinces are colored using `d3.scaleOrdinal` with `schemeCategory10`, and hover effects change fill to red. The visualization relies on `d3.geoPath`, `d3.geoCentroid`, and `d3.zoom` for interaction.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1c276932274047609f7cef48f7f9e578?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
