{"version":"1.0","type":"rich","title":"Choropleth Map with Interactive Filtering","description":"This choropleth map colors world countries by their economy type, with a color legend that supports interactive filtering. Clicking a legend category highlights matching countries and dims all others, while a zoomable natural Earth projection enables pan and scale exploration. Built with React and D3 v5, it uses `geoNaturalEarth1` and `geoPath` for map rendering, `scaleOrdinal` with `schemeSpectral` for color mapping, and `zoom` for interaction. Country data is loaded from the World Atlas TopoJSON and TSV files.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3260b512fb6c4c01b5b2a8566b1cb216?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
