{"version":"1.0","type":"rich","title":"Choropleth","description":"This choropleth visualizes countries colored by economic classification using an ordinal color scale derived from d3.scaleOrdinal and d3.schemeSpectral. It renders a Natural Earth projection with d3.geoNaturalEarth1 and d3.geoPath, loading world geometry via TopoJSON from the world-atlas package, with country names and economic data matched from a TSV table. A custom color legend, built with D3 selections, displays the sorted categories, and d3.zoom enables panning and zooming of the map.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bb7af83ceca54182921a6e56665713b4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
