{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This choropleth map visualizes global economic data by coloring countries according to a categorical color scale. Users can click legend entries to highlight countries matching the selected category, dimming all others. Built with D3 v5, it uses `d3.geoPath` with a Natural Earth projection and `d3.scaleOrdinal` for coloring. The map loads country boundaries and economic classifications from a world-atlas TopoJSON dataset, while the interactive legend and country paths are rendered as SVG elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e127d7f6588a4a78bec4d5abc95af79c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
