{"version":"1.0","type":"rich","title":"中国地图","description":"A choropleth map of China renders each province as an SVG path using a Mercator projection centered on the country. The D3.js code loads GeoJSON map data and applies a categorical color scale, with provinces highlighted yellow on mouseover. Province names are positioned using projected centroid coordinates, with a vertical offset applied to prevent overlap between Macau and Hong Kong labels. The visualization demonstrates D3’s geographic path generator (`d3.geoPath`) and projection utilities.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8240f6bb60f746a286a1a8fd5e9c9b89?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
