{"version":"1.0","type":"rich","title":"Fork of Choropleth Map with Interactive Filtering","description":"This interactive choropleth map displays the world’s countries colored by their economic classification, with a color legend that filters the map when clicked. Clicking a legend value highlights corresponding countries and dims all others; clicking again clears the filter. Hovering a country reveals its name and value in a tooltip. Built with D3 v5, it uses `d3.geoNaturalEarth1` for projection, `d3.geoPath` to render country paths, and a custom `colorLegend` module for the clickable legend. Data comes from the world-atlas TopoJSON and TSV files, rendered as SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cc3e8771e047410488b98ce277e8c5f9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
