{"version":"1.0","type":"rich","title":"Choropleth Map","description":"A choropleth map colors countries by their economy category using an ordinal color scale derived from the World Atlas TopoJSON dataset, which is joined with tab-separated metadata. The visualization uses d3.geoPath with a Natural Earth projection and supports zooming via d3.zoom. A custom color legend, built with SVG circles and text, displays the color scale categories. Countries are interactive, showing their name and economy group in a tooltip on hover, with a red highlight effect.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5c897181f0334f99ab56e532a339ebc2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
