{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This visualization shows the hierarchical organization of world countries, grouped by continent and subregion, as an interactive tree diagram. Using d3.js v5, it employs a tree layout with horizontal links to radiate country names from a central root, with node text sized inversely to depth. The SVG scene supports zooming and panning via d3.zoom, and the data structure follows a JSON nested format with countries as leaf nodes under regional groupings.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0de34e3aea464ebd8ce09447b6ebcfe1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
