{"version":"1.0","type":"rich","title":"Fork of Choropleth Map","description":"This choropleth map colors countries by their economy category using a categorical ordinal scale with a spectral color scheme. The visualization is built with D3 v5, using `geoNaturalEarth1` and `geoPath` for the map projection, with TopoJSON world data loaded from the world-atlas package. Interactive zoom is implemented via `d3.zoom`, while a custom color legend component renders ordinal categories with circles and labels. Country data is enriched by joining ISO codes from a TSV file, revealing the economy groups on hover via tooltips.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ac43a7969b604d9799284529a951cd5e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
