{"version":"1.0","type":"rich","title":"Swanton's Travels","description":"A choropleth map displays world countries colored by income group, with a color legend for filtering. Clicking a country highlights it and dims all others; clicking again resets. The map uses D3's `geoNaturalEarth1` projection with `geoPath` for rendering shapes, and supports zooming via the `zoom` event. Data is loaded from a CSV of travelers and a TopoJSON world atlas, processed with `topojson.feature`. An ordinal spectral color scale maps economy categories.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7679effb31b843c0aff8598eac19e0e4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
