{"version":"1.0","type":"rich","title":"Fork of Choropleth Map","description":"This example displays a choropleth map of China’s provinces, colored by economic group using an ordinal color scale from `d3.scaleOrdinal` and `schemeSpectral`. It renders geographic boundaries with `d3.geoPath` and a natural Earth projection, and supports interactive pan and zoom via `d3.zoom`. A legend, built with custom SVG circles and text, shows category colors. Province data comes from a local `chinaMap.json` file, with additional metadata merged from a TSV source.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/63ebc3bcde8e459caff0a3d469236d77?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
