{"version":"1.0","type":"rich","title":"Choropleth Map with Interactive Filtering","description":"This choropleth map uses colors to display the economy category of each country, with an interactive color legend that filters the map. Clicking a legend item dims all countries not in that category, while hovering over a country turns it red. Built with D3 v5, the visualization uses `geoPath` and `geoNaturalEarth1` for map projection and `scaleOrdinal` with `schemeSpectral` for coloring. The code loads world country boundaries from TopoJSON and economy data from a TSV file using `d3.tsv` and the `topojson` library.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/533ec88004434997bf84ae3924314e29?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
