{"version":"1.0","type":"rich","title":"Swanton Choropleth Map","description":"This choropleth map uses color to depict the economic classification of each country, rendered as an SVG via D3's `geoPath` and `geoNaturalEarth1` projection. Hovering a country turns it gray and reveals its name and economy in a tooltip. The map loads world geography and tabular data from the world-atlas package, and displays a color legend built with custom `colorLegend` logic. The visualization supports zooming and panning through D3's `zoom` component.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/43ac1097f8b74ac788c7516ebc6c03dc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
