{"version":"1.0","type":"rich","title":"Building a Tree Visualization","description":"This visualization displays a hierarchical tree of world geography, showing continents divided into subregions and then individual countries. The layout uses a horizontal tree structure where parent nodes are centered above their children, with curved links connecting each level. The code leverages D3 v5’s `tree` and `hierarchy` layouts, along with `linkHorizontal` for the curved paths, and renders text labels with font sizes that shrink with each depth level. The SVG scene supports zooming and panning through D3’s `zoom` behavior, with data loaded from a JSON file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4c776ff6f39447858cc0203f4ec9a6e5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
