{"version":"1.0","type":"rich","title":"Swanton Choropleth Map With Interactive Filtering","description":"A choropleth map of the world colors each country by its economy type using a spectral ordinal color scale derived from World Atlas TopoJSON data. Interactive filtering dims non-selected countries and highlights the chosen economy when a legend swatch is clicked. The visualization uses D3 v5 APIs including `geoNaturalEarth1`, `geoPath`, and `zoom` for panning, while the legend handles click events to toggle the filter. The SVG rendering includes hover effects, tooltips, and a semi-transparent background.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d8e83e940b8b48479a8ffc11bdb459ec?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
