{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This choropleth map colors world countries by their economy category using an ordinal color scale with a spectral scheme. The visualization supports zooming and panning through d3.zoom, while d3.geoNaturalEarth1 and d3.geoPath render the geographic features from TopoJSON world-atlas data joined with TSV country metadata. Countries display a tooltip with their name and economy value on hover, and a custom color legend built with SVG circles and text shows the category mapping.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/41951db54578497ea37f7fb30ec7f966?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
