{"version":"1.0","type":"rich","title":"Choropleth Map with Interactive Filtering","description":"A choropleth map displays global economic classifications, with countries colored via an ordinal spectral scale from World Atlas TopoJSON and TSV data. Hovering a legend item filters the map, dimming non-matching countries to 0.1 opacity and highlighting matches, while clicking toggles the filter. Built with `d3.geoNaturalEarth1`, `d3.geoPath`, `d3.zoom`, and `d3.scaleOrdinal`, the SVG renders country paths and a custom color legend with interactive `onClick` handlers.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5c56a5288fc84c49bb3cd697a6a01243?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
