{"version":"1.0","type":"rich","title":"Choropleth Map with Interactive filtering","description":"This choropleth map displays world economies using a color gradient, with an interactive legend that filters countries by economic category. Users can zoom and pan the map, and clicking a legend entry dims non-matching countries while highlighting the selected group. The visualization uses d3.geoNaturalEarth1 projection, d3.geoPath for rendering SVG paths, and d3.zoom for navigation. Data comes from the world-atlas TopoJSON and TSV datasets, with unemployment type and population shown in tooltips. The color scale uses d3.schemeSpectral, and legend interactions are handled through d3 event listeners.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/64c535f8dae845019ae263676e2b5734?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
