{"version":"1.0","type":"rich","title":"Choropleth Map with Interactive Filtering","description":"A choropleth map of global economies uses color to distinguish categories, with an interactive legend enabling users to click a category and highlight matching countries while dimming the rest. Built with D3 v5, the visualization uses `geoNaturalEarth1` and `geoPath` for map projection, `scaleOrdinal` and `schemeSpectral` for coloring, and `zoom` for panning. Data comes from the World Atlas TopoJSON and TSV files. Hovering reveals country names and values via SVG `title` elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0efcaca6aa89448b87f0262fd7e9d04a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
