{"version":"1.0","type":"rich","title":"Choropleth Map with interactive filtering","description":"This choropleth map displays world countries colored by income group using an ordinal color scale, with a zoomable, panning natural Earth projection. Clicking a legend swatch filters the map by highlighting matching countries and dimming others. The visualization uses d3.geoNaturalEarth1, d3.geoPath, and d3.zoom for map interaction, while a custom colorLegend component handles click-driven filtering. Data comes from the world-atlas TopoJSON and TSV files, with countries rendered as SVG paths and hover effects changing fill color.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c6879c3ebc634f4db49b2af84a53ad58?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
