{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This choropleth map uses color to encode the economy classification of countries, sourced from world-atlas TSV data matched with TopoJSON geometries. D3’s `geoNaturalEarth1` projection and `geoPath` render country outlines as SVG paths, while a sequential spectral color scale (`schemeSpectral`) fills each territory. An interactive zoom control, built with D3’s `zoom` event, adjusts the projection transform, and a custom legend (from `colorLegend.js`) displays the ordinal scale’s categories with hover effects highlighting individual countries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/51654f98f4db476a88e0ed66d3a56359?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
