{"version":"1.0","type":"rich","title":"Collapsible Tree Version 1","description":"A collapsible tree visualizes the hierarchical structure of the flare-2.json dataset, with nodes representing categories and leaves showing values. Clicking a node expands or collapses its children, triggering smooth animated transitions. The implementation uses D3 v6 with `d3.tree` and `d3.linkHorizontal` to compute the layout, while `d3.zoom` enables pan and zoom. Node and link updates are animated via `transition.attr`, with SVG circles and text elements rendering the hierarchy.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e5de175b69c14c91a6cee7033ce7af06?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
