{"version":"1.0","type":"rich","title":"Chorpleth Map with Interactive Filtering","description":"This choropleth map colors countries by their economy category using a spectral color scale, with a legend that filters the map by clicking on a category. The map renders with SVG paths via `d3.geoPath` and the Natural Earth projection, while the legend uses `d3.scaleOrdinal` and `d3.schemeSpectral` for color assignment. Interactive filtering dims non-selected countries and legend entries, and hovering reveals country names and values through SVG `title` elements. Country boundaries come from the world-atlas TopoJSON dataset merged with TSV metadata.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/afb3e28a19ec4cd5990784bc78c2bf0a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
