{"version":"1.0","type":"rich","title":"World Countries Tree","description":"The World Countries Tree shows a hierarchical organization of words extracted from a dataset of text entries. Each node is labeled with a short list of keywords, and parent-child relationships create a branching tree structure. The visualization uses D3.js v5 with an SVG rendering and a horizontal link diagram. It employs the `d3.tree` layout and `d3.linkHorizontal` generator to draw the paths, while `d3.zoom` enables interactive pan and zoom on the canvas. Node text size scales with depth, and all labels are styled with the Playfair Display font.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6ce7c40a2d2540588c86c3186e619387?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
