{"version":"1.0","type":"rich","title":"Swanton Choropleth Map","description":"This choropleth map visualizes global income groups, coloring each country according to its income_grp category with a spectral color scale. The map uses a natural Earth projection and supports zooming via the zoom API, while a legend explains the color categories. The visualization loads world country geometries from the world-atlas TopoJSON and TSV datasets, processes them with topojson.feature, and renders the paths using d3.geoPath. Hovering highlights a country in gray and reveals a tooltip with its name and income group.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a2cfde06bc7344cdbf25dfbfdc185a6b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
