{"version":"1.0","type":"rich","title":"Choropleth Map with Interactive Filtering","description":"A world choropleth map colors countries by economic classification, with a linked legend that filters the map when a category is clicked. Hovering over the legend dims non-matching countries to 10% opacity, while the selected category is highlighted. The visualization uses D3 v5’s `geoNaturalEarth1` projection, `geoPath`, and `zoom` for panning, alongside a custom ordinal `scaleOrdinal` with the `schemeSpectral` range. Map data comes from the World Atlas TopoJSON and TSV files.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9a02493f60c244b3855751bdab753c80?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
