{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This choropleth map visualizes world economies by coloring each country according to its economic classification, using a spectral color scale created with `d3.scaleOrdinal` and `schemeSpectral`. The map renders as an SVG using `d3.geoPath` with the Natural Earth projection, displaying country data loaded from the world-atlas TopoJSON and TSV files. Interactive zooming via the `zoom` event lets users explore regions, while a custom `colorLegend` function shows the categorical color assignments.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bdf86e1d43024ac1ba154779ab168825?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
