{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This example displays a world map as a choropleth, with each country colored by its income group using an ordinal color scale and a custom SVG legend. D3’s `geoNaturalEarth1` projection and `geoPath` render geographic boundaries from a TopoJSON source, while data from a TSV file is joined by country ID. Hovering a country turns it red and shows its name and income group in a tooltip, and pan/zoom interaction is enabled via a custom zoom event.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e11000dfbaa84079838c790fb1a01ded?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
