{"version":"1.0","type":"rich","title":"Fun Family tree in d3.js","description":"This interactive family tree visualization in D3.js v3 displays hierarchical relationships among named individuals, with expandable and collapsible nodes. Clicking a node toggles its children, animating the tree’s layout with smooth transitions. The SVG-based chart uses `d3.layout.tree` for positioning and `d3.svg.diagonal` for curved links. Built with React, it renders circular nodes with labels and color-coded states, animating position changes via `transition` over 750 milliseconds.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/599867fcb3b94ade8afcf14a3f009457?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
