{"version":"1.0","type":"rich","title":"Choropleth Map Interactive","description":"This interactive choropleth map displays countries colored by their economy category, using a spectral color scale and a natural Earth projection. Users can click legend swatches to highlight matching regions while dimming others. The visualization is built with D3 v5 modules including `geoNaturalEarth1`, `geoPath`, and `zoom`, rendering vector shapes as SVG. It loads geographic data from the World Atlas TopoJSON and TSV files, processing them via `topojson.feature`. A dedicated color legend component supports selection filtering, while CSS hover effects emphasize individual countries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7de079a2d44d4e42829ca614da26402a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
