{"version":"1.0","type":"rich","title":"D3.js collapsible tree with boxes","description":"This example presents a collapsible tree visualization generated from a JSON data structure, using D3.js v3. The tree is rendered as a series of connected boxes, each representing a node, and users can click on nodes to expand or collapse their children. The layout is computed with `d3.layout.tree`, and the visualization includes interactive zooming and panning through `d3.behavior.zoom`. Node colors are assigned based on their depth in the tree, and tooltips provide additional details. The entire scene is drawn as an SVG with animated transitions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8386ab5bd41b42769ccbaa451ceac3f6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
