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.
