{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This choropleth map displays global economic classifications by coloring each country according to a categorical ordinal scale derived from the `economy` property in the world-atlas dataset. The visualization loads TopoJSON and TSV data, then uses `d3.geoPath` with a natural Earth projection to render country boundaries, while a custom color legend built with SVG circles and text explains the color encoding. Users can zoom and pan via `d3.zoom`, with hover effects highlighting individual nations.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e34882ae1bb644a6987f2f6f988f7712?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
