{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This choropleth map colors countries by their economy classification, using a sequential spectral color scale to distinguish categories. The visualization renders geographic boundaries with `d3.geoPath`, projecting the world using the Natural Earth projection and enabling zoom and pan through `d3.zoom`. The code loads world topology from TopoJSON and joins it with TSV metadata via `d3.tsv`, while a custom color legend component displays the categorical scale. Hovering highlights individual countries in red, and the map includes data from the world-atlas dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d2fae1dcf9514e7a96c38ae7fa5aee28?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
