{"version":"1.0","type":"rich","title":"Fork of Choropleth Map with Interactive Filtering F","description":"This choropleth map displays global country-level economic classifications using an ordinal color scale. Users can click legend items to highlight matching countries and dim all others, with a second click clearing the filter. The map uses D3 v5’s `geoNaturalEarth1` projection, `geoPath`, and `zoom` for pan/zoom interaction, with SVG rendering. Data comes from the world-atlas TopoJSON dataset, joined to TSV metadata. The legend and map are both rendered with D3 selections, and hover effects highlight individual countries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2722a9dae15e4b4ebd880e45fcb60561?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
