{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This choropleth map displays world countries colored by economic classification using an ordinal color scale with a spectral palette. The visualization renders geographic boundaries through a natural Earth projection and topojson-processed data, with country names and economic groups shown on hover via SVG title elements. Built with D3 v5, the example uses `d3.geoPath` for map geometry, `d3.scaleOrdinal` for color mapping, and a custom legend component that visualizes discrete color categories. A zoom behavior enables interactive panning, while hover effects highlight individual countries in red.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a20ed864ed294c6291bc97403507ecc8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
