{"version":"1.0","type":"rich","title":"Tree Example","description":"This example shows an interactive family tree built with D3.js, displaying a hierarchical dataset of names and parent-child relationships. The visualization uses the `d3.layout.tree` layout to position nodes and `d3.svg.diagonal` for the curved links between them. Each node is rendered as an SVG circle with a text label, and clicking on a node toggles its children, collapsing or expanding that branch. The nodes and links animate smoothly via transitions, with colors indicating different levels in the hierarchy.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ac4ce4fc42ed46ce9bfaa96ff9ab2e2a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
