{"version":"1.0","type":"rich","title":"Tree Example","description":"This example shows a collapsible tree diagram built with D3.js, displaying hierarchical data with nodes for “Grand parent,” “Parent A,” and “Parent B.” Clicking a node toggles its children, animating the layout transitions over 750 milliseconds. The visualization uses `d3.layout.tree` for positioning, `d3.svg.diagonal` for curved links, and SVG circles and text for nodes. Data is hardcoded in a JavaScript array, rendered with React-style CSS classes and pointer cursor interactions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ceb9be559af44adfa2be1193e6a50092?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
