{"version":"1.0","type":"rich","title":"Tree Example","description":"This example shows an interactive family tree using a hierarchical node-link diagram, with each person represented as a colored circle and labeled with their name. The tree is built from a static JavaScript array and rendered with SVG, where nodes collapse and expand on click, and transitions animate position changes over 750 milliseconds. Using D3.js version 3’s `d3.layout.tree` and `d3.svg.diagonal`, the code computes the layout and draws curved links, while node fill and stroke colors encode the person’s type and level fields.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f48532891a2e448c99bdfc4e0f2a9654?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
