{"version":"1.0","type":"rich","title":"[REDO] Interactive Filtering","description":"A choropleth map of world countries colored by economic classification demonstrates an interactive filtering technique. Users can click a legend to highlight matching countries while dimming others, with a second click restoring full visibility. The visualization uses d3.geoPath with a geoNaturalEarth1 projection to render country boundaries, while a custom colorLegend component manages the categorical color scale. Input data comes from the world-atlas TopoJSON and TSV files, processed through the topojson feature API.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2b78fc5832ec4e5eb728627241f44bab?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
