{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This choropleth map colors countries by economic group, drawing from world-atlas TopoJSON and TSV data joined by country ID. The visualization renders the map with D3’s `geoNaturalEarth1` projection and `geoPath` generator, while an ordinal color scale from `schemeSpectral` assigns shades to each group. A custom color legend displays every category with circles and labels, and users can zoom and pan via D3’s `zoom` event, which updates the group’s transform. Hovering a country highlights it in red and shows its name and economy in a tooltip.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5c621ba088a74685aacfe6b5b3d56875?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
