{"version":"1.0","type":"rich","title":"Collapsible Tree Hierarchy - Real Data","description":"A collapsible tree hierarchy displays real hierarchical data, with nodes that expand and collapse on click. It also enables navigation by re-rooting the tree view to the clicked node, while a stack tracks the path back to previous roots. The visualization uses d3.v6’s tree layout and transitions, rendering SVG circles and text labels with animated updates. A node-info div shows details for the selected item, and the canvas height dynamically adjusts to fit the visible hierarchy.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4a3292e795704aeaaa8be734f0c2e701?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
