{"version":"1.0","type":"rich","title":"Tree","description":"A horizontal tree diagram visualizes hierarchical data with color-coded nodes representing question-answering states. Users toggle node expansion by clicking, with smooth transitions animating node positions and link paths. The visualization uses D3 v5's `tree` layout, `hierarchy` function, and `linkHorizontal` generator to compute the layout, while SVG elements and `transition` handle the rendering and animation. Interactive zooming is supported through the `zoom` API. The dataset comes from a static JavaScript object defining a tree structure with visit, attempt, and correctness classifications.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d78373c1c15547e791f454f4bd2cb73a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
