{"version":"1.0","type":"rich","title":"d3 Choropleth Map with Interactive Filtering","description":"This choropleth map displays global economic classifications by country using color-coded regions. Users can filter the map by clicking legend categories, which dims non-matching countries and highlights those with the selected value. The visualization uses d3.geoPath with a geoNaturalEarth1 projection to render SVG map paths, while d3.scaleOrdinal and schemeSpectral assign colors. Data is loaded from world-atlas TopoJSON and TSV files, and interactions rely on the d3.event zoom and legend click handlers.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/69719c8874f8422fbbbdcc27369a0743?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
