{"version":"1.0","type":"rich","title":"Choropleth Map with Interactive Filtering","description":"This interactive choropleth map displays world economic data using a D3.js SVG rendering with a `geoNaturalEarth1` projection and `geoPath`. A spectral ordinal color scale maps each country's economy category. Users can hover over legend items to filter the map, dimming non-selected countries to 10% opacity while highlighting matching ones. The visualization uses `d3.scaleOrdinal`, `d3.schemeSpectral`, and a custom `colorLegend` module, loading data 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/43bef31ccdf74795863dcc3197939f75?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
