{"version":"1.0","type":"rich","title":"Choropleth Map with Interactive Filtering","description":"This choropleth map visualizes global economic classifications by country, with interactive filtering through a clickable color legend that updates the displayed data. The map uses a dark-blue sphere background with semi-transparent colored regions, rendered via SVG paths generated by `d3.geoPath` with an Equal Earth projection. Users can zoom and pan using `d3.zoom`, while the legend employs `d3.scaleOrdinal` with a spectral color scheme and animated transitions. Data combines TopoJSON country boundaries from world-atlas with TSV metadata, processed through `Promise.all` and the `feature` API.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/635845fd4c8b4917b999b18cab5e9b09?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
