{"version":"1.0","type":"rich","title":"Choropleth Map with Interactive Filtering","description":"A choropleth map displays world countries colored by their economy category, which can be interactively filtered by clicking entries in an adjacent color legend. The map renders geographic boundaries using `d3.geoPath` with a `geoNaturalEarth1` projection, and supports panning and zooming through `d3.zoom`. Clicking a legend item, built with `d3.scaleOrdinal` and `schemeSpectral`, dims non-matching countries while highlighting the selected group. The data comes from the world-atlas TopoJSON and TSV files, with the visualization built using D3 v5 and SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/10d820dea0034deebb37d685a70127ff?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
