{"version":"1.0","type":"rich","title":"Affection Type Social Map","description":"A choropleth map of China displays each province colored by category, overlaid with circles sized by social affection values using a square-root scale. The map uses `d3.geoMercator` projection and `d3.geoPath` to render province boundaries from TopoJSON data, while CSV data is merged with geographic features. A custom legend built with `d3.scaleSqrt` and `sizeLengend` shows circle radius mappings. Hovering highlights provinces, and the SVG rendering uses D3 v5 with `d3.csv` and `d3.json` for data loading.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2dbbf50eb0d94375aebc602a9d48c2e8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
