{"version":"1.0","type":"rich","title":"Interactive Tree","description":"This interactive tree visualizes question-answering outcomes, starting from a \"Faced Questions\" root that branches into Visit/Not Visit, Attempted/Not Attempted, and Correct/Incorrect paths, each colored by status. Clicking a node collapses or expands its subtree, while dragging attempts deletion. Built with D3 v5, it uses `d3.tree` for layout, `d3.hierarchy` for data binding, `d3.linkHorizontal` for edges, and SVG elements with zoom support via `d3.zoom`. Transitions animate node positions and opacity changes over 100ms durations.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3e811fc4e25a4b23b1e65e6d81f1e5c8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
