{"version":"1.0","type":"rich","title":"Collapsible Tree","description":"This interactive visualization displays a hierarchical tree of building resource consumption, with energy and water data from a facility management system. Users can click on parent nodes to expand or collapse branches, dynamically updating the layout. Built with D3 version 3, it uses the `d3.layout.tree` API to compute a Reingold–Tilford layout and `d3.svg.diagonal` for curved links. SVG elements transition smoothly to new positions using `transition()` with 750ms animations.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-47ef83c4bdfd14e6110d3406048feccb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
