{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This choropleth map visualizes the world's countries, colored according to their economic classification. The map uses D3's `geoNaturalEarth1` projection and `geoPath` to render the geographic shapes, with an ordinal color scale based on a spectral scheme to represent the data. Country data comes from the world-atlas dataset, which merges TopoJSON geometry with TSV metadata. Interactive features include zooming via `zoom()` and a color legend built with `scaleOrdinal` and SVG elements. Hovering over a country highlights it in red and displays a tooltip with its name and economic group.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dd1b196aa56f495c911507f43ed5411c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
