{"version":"1.0","type":"rich","title":"Affection Type Travel Map","description":"This map visualizes travel-related affection types across Chinese provinces, using circle size overlaid on geographic regions to represent the number of travel records per province. The choropleth-style fills assign each province a categorical color based on its ID. Built with D3 v5, the visualization loads CSV data and TopoJSON geometry, then projects the map using `d3.geoMercator` and renders paths with `d3.geoPath`. Circle radii derive from a square-root scale, and a custom legend component displays tick values with formatted labels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/392f29c76e124c0da78d82a3b6d4a6f7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
