{"version":"1.0","type":"rich","title":"Choropleth Map","description":"A choropleth map colors countries by economic classification using an ordinal color scale derived from world-atlas data. The visualization renders geographic boundaries with `d3.geoPath` and a natural Earth projection, while a custom color legend explains the categorical mapping. Pan and zoom interactions are enabled via `d3.zoom`, and hover effects highlight individual countries. The map uses TopoJSON for country outlines and TSV metadata for economy labels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d1e5d47590eb4367855d53abea7b7e81?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
