{"version":"1.0","type":"rich","title":"Choropleth Map","description":"A choropleth map of the world colors each country by its economy category, with a legend showing the ordinal color scale. The visualization uses D3.js with a natural Earth projection and topojson for geographic data. Hovering over a country highlights it in red and displays a tooltip with its name and economy value. The map features zooming via D3’s zoom event, and the color legend is built from D3’s `scaleOrdinal` with blue color schemes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a68215494d70433f88674665ca3eb743?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
