{"version":"1.0","type":"rich","title":"Simple Collapsible Tree","description":"This interactive visualization displays a hierarchical tree that expands and collapses when nodes are clicked. The tree uses a horizontal layout with circular nodes and text labels, and collapsible branches animate smoothly via transitions. The code employs D3 v3’s `d3.layout.tree` for positioning and `d3.svg.diagonal` for link paths, with sample data from a manual tree structure containing \"Top Level\" and dummy child nodes. SVG elements provide the rendering, and animations use `transition().duration()` to update node positions on interaction.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6130f96fe6674d40956b0fb43ac25bfe?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
