{"version":"1.0","type":"rich","title":"Tree Example","description":"This example displays an animated, collapsible tree diagram representing a three-level family hierarchy, with nodes showing names and links connecting parents to children. Clicking a node toggles the visibility of its subtree, smoothly transitioning the layout as branches expand and collapse. Built with D3.js version 3.5.17, the visualization uses the `d3.layout.tree` and `d3.svg.diagonal` APIs to compute the node positions and draw curved link paths, while SVG transitions animate the changes over 750 milliseconds. The data is hardcoded as a nested JavaScript array in the HTML file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2b080941a5b045658fb48d1ffd2e5e30?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
