{"version":"1.0","type":"rich","title":"Zoom Capability of Art Tree","description":"This visualization presents a hierarchical tree of world regions and countries, arranged using the `d3.tree` layout and rendered as SVG. Users can pan and zoom the entire structure through the `d3.zoom` API, which updates a transform group. The hierarchy is loaded from a JSON file, with links drawn via `d3.linkHorizontal` path generators and text labels styled with font sizes that scale by node depth. The code relies on D3 v5 for DOM selection, data binding, and zoom event handling.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/33a10e5c31ab43569fa59a92b3157e3c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
