{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"This visualization presents the hierarchical structure of world countries as an interactive tree diagram, organized by continent and subregion before listing individual nations. Using D3 v5’s `tree` layout and `linkHorizontal` path generator, the SVG renders curved links and text labels, with font size scaling by node depth. Pan and zoom functionality is enabled via the `zoom` behavior, allowing users to explore the full dataset loaded from `data.json`. The data is drawn from a static JSON file, and the styling employs the Playfair Display font with teal link strokes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a5962f29c024467296f5439e5c165612?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
