{"version":"1.0","type":"rich","title":"Choropleth Map with Interactive Filtering","description":"This choropleth map displays country-level economic classifications using a color scale based on world-atlas TopoJSON data. Users can click legend items to highlight countries matching that category while dimming others, and hover effects further emphasize individual countries. The visualization uses d3.geoPath with a geoNaturalEarth1 projection for map rendering, d3.zoom for panning and zooming, and d3.scaleOrdinal with schemeSpectral for color encoding. The legend and map are built as separate SVG components that re-render when the selection changes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b5af8bf1477648cd86164fb63dbc2878?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
