{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"This fork of D3's tree diagram displays a hierarchical breakdown of world countries, organized by continent and subregion, with all terminal nodes labeled in a serif font. The visualization is rendered as an SVG, with nodes positioned horizontally based on depth. The code uses D3 v5’s `tree` layout, `hierarchy` and `linkHorizontal` helpers to compute paths, and a `zoom` interaction that rescales the entire drawing on user input. Text size scales inversely with depth, and link paths are styled with a teal stroke.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/62134482aa9d43c29c3a8cbbb4f33615?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
