{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This visualization presents a hierarchical tree of world countries, organized by continent and region, with each node labeled by name. Built with D3 v5, it uses the `tree` layout and `linkHorizontal` generator to draw the branching structure, while `zoom` enables panning and scaling. The SVG renders text labels with font sizes decreasing by depth, and the data comes from a local JSON file. The layout positions nodes with `d.x` and `d.y` coordinates from the hierarchy layout.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6b60a3081b334c05bac9a7d049e0ee08?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
