{"version":"1.0","type":"rich","title":"Fork of Choropleth Map with Interactive Filtering","description":"This choropleth map visualizes global economic classifications with an interactive color legend that filters countries by category. Clicking a legend item highlights matching countries while dimming others, and clicking again removes the filter. The map uses D3 v5 with `geoNaturalEarth1` projection, `geoPath`, and zoom behavior, while the legend leverages `scaleOrdinal` with `schemeSpectral` colors. Data comes from the World Atlas TopoJSON and TSV files, rendered as SVG with hover tooltips showing country names and values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9f303c31731944baa5917e6a6e119c9f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
