{"version":"1.0","type":"rich","title":"World Map","description":"This example presents a choropleth world map visualizing countries colored by income group, with data sourced from World Atlas TopoJSON and TSV files. It uses D3 v5 with a geoNaturalEarth1 projection and d3.geoPath to render countries, while a color legend explains the ordinal color scale. The map supports zooming via d3.zoom, and hovering highlights countries in green. Animated transitions update the legend circles when the scale changes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4c9f6f071ccf48d39088aa270d0d5a97?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
