{"version":"1.0","type":"rich","title":"Fork of Choropleth Map","description":"This choropleth map colors countries by economic classification using a categorical ordinal color scale derived from d3.scaleOrdinal and d3.schemeSpectral. The visualization renders geographic shapes with d3.geoPath and a natural Earth projection, while supporting interactive pan and zoom via d3.zoom. Data comes from the World Atlas TopoJSON and TSV files, loaded through d3.json and d3.tsv. A custom d3 color legend with circles and labels appears on the left, and hovering highlights individual countries in red.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/49421451ba9547e486fe0d367aced135?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
