{"version":"1.0","type":"rich","title":"Choropleth Map with Interactive Filtering","description":"This choropleth map visualizes the world's economies, coloring each country according to its economic classification. Users can zoom and pan the map via `d3.zoom`, while the color legend offers an interactive click handler, though its filtering effect is not implemented. The visualization loads geographic data from the world-atlas TopoJSON and TSV files, using `d3.geoPath` with a `geoNaturalEarth1` projection to render countries as SVG paths. A spectral color scale maps economy categories to hues, and hovering highlights a country in coral.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0add4f3991bc4354b5f29f21d4c9df81?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
