{"version":"1.0","type":"rich","title":"Fork of Choroplath Map with Interactive Filtering","description":"This interactive choropleth map colors countries by economic classification using a categorical color scale and topojson data from the World Atlas. Users click the color legend to filter the map, which dims non-matching countries and highlights the selected category via the `onClick` handler. Pan and zoom are enabled with `d3.zoom` and `d3.geoNaturalEarth1` projection for the SVG paths. The legend and map communicate through a shared `selectedColorValue` state, with opacity transitions driven by the color scale.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/91f9410ef3894c1c9b53204cba0b4a73?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
