{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This visualization presents a hierarchical tree of world countries, organized by continent and subregion, using data from a JSON file. The tree is rendered with branching paths and text labels for each node, with font size scaling by depth. Built with d3.js v5, it uses the `tree`, `hierarchy`, `linkHorizontal`, and `zoom` components to layout and draw the structure, with the zoom feature allowing interactive panning and scaling of the view. The SVG output is styled with a custom serif font and hover-free text shadows.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/322bf5401dda42318bdc558b92c5c7cf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
