{"version":"1.0","type":"rich","title":"Choropleth Map with Interactive Filtering","description":"This choropleth map displays global economies using color-coded countries, with interactive filtering through a clickable color legend. Hovering over legend items dims non-matching countries, while clicking toggles filtering and highlights selected categories. The visualization uses d3.geoPath with a geoNaturalEarth1 projection for map rendering, d3.scaleOrdinal with schemeSpectral for coloring, and d3.zoom for panning. Data comes from TopoJSON world-atlas files, with country names and economy classifications merged from TSV metadata.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ba38a271291d4b9f87f774134e3ce5a7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
