{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"This tree visualization displays a hierarchical dataset of human goals and activities, loaded from local JSON. The graph uses a horizontal dendrogram layout with curved link paths generated by `d3.linkHorizontal`. Node labels are positioned dynamically, with font size scaling inversely to node depth. The SVG canvas is rendered with a light theme using the Playfair Display serif font, and pan/zoom interactions are enabled via the `d3.zoom` API. A video tutorial in the README accompanies the code, which relies on `d3.hierarchy` and `d3.tree` for the layout.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e47cc652aa514e579625a002428d6e0d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
