{"version":"1.0","type":"rich","title":"Choropleth Map with Interactive Filtering","description":"A choropleth map displays world countries colored by an economic attribute, with interactive filtering that highlights selected categories and dims others. The map uses a natural Earth projection with a shadowed sphere, while a clickable color legend controls which categories remain prominent. Built with D3 v5, the visualization uses `d3.geoPath`, `d3.geoNaturalEarth1`, and an ordinal color scale based on spectral schemes. Data is loaded from the world-atlas TopoJSON and TSV files, with zooming enabled via D3's `zoom` component.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/de8492ea20cd4c09bb84819620fca911?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
