{"version":"1.0","type":"rich","title":"Choropleth Tutorial - Leaflet","description":"A choropleth map visualizes food-safety inspection counts across Chinese provinces, with hover interactions revealing province names and defect quantities. Built with Leaflet and D3 v5, the map loads GeoJSON boundaries from `china.js` and applies a color scale based on population density data. Additional charts—a word cloud and two pie charts—are embedded via Observable iframes, while a legend and dynamic tooltip enhance readability. The project integrates Vue as part of its framework stack.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dec05d3584f64ee6a7f29bdf7d58e7d6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
