{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This visualization displays the hierarchical structure of world countries, organized by continent and subregion. The code uses D3’s `tree` layout and `linkHorizontal` generator to draw the branching paths, with text labels positioned at each node. Data is loaded from a local JSON file via `d3.json`, and zooming is enabled through D3’s `zoom` behavior. The SVG is styled with a Playfair Display font, and node text size decreases with depth.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1452cd949f204e86871ea8051b864f7a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
