{"version":"1.0","type":"rich","title":"Tree Example","description":"This interactive tree diagram displays hierarchical data with collapsible nodes. The visualization uses the D3.js library (version 3.5.17) with a static JSON dataset containing a root node and its descendants. The code employs `d3.layout.tree` for layout computation and `d3.svg.diagonal` for link rendering. Users can click nodes to expand or collapse subtrees, triggering smooth animated transitions via D3's `.transition()` method. The SVG rendering includes styled circles and text labels, with nodes colored steelblue or lightsteelblue depending on collapsed state.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1fd314a03c0d4717b1bb11443d6d70ec?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
