{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This visualization displays a hierarchical tree of world countries, organized by continent and subregion, with each node labeled by name. It uses D3 v5's `tree` layout and `linkHorizontal` generator to draw curved paths between parent and child nodes, while `zoom` enables panning and scaling. The SVG rendering applies a serif font and a teal stroke color, with node text sized by depth. Data is loaded from a local JSON file, making the structure purely hierarchical rather than geographic.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/38ebddbc885548a38a7b137f90df1df9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
