{"version":"1.0","type":"rich","title":"Family Tree_lewis","description":"This example shows an interactive family tree visualization built with D3.js, displaying hierarchical relationships among family members using a collapsible tree layout rendered as SVG. The visualization loads JSON data containing the family structure and renders each person as a colored, clickable node connected by labeled links, with names and relationships displayed inline. Using D3 v3’s tree layout, the code dynamically computes node positions, applies zoom and drag behavior via `d3.behavior.zoom`, and animates node expansions and collapses with `transition.attrTween`. Tooltips appear on hover, and the tree supports mouse-wheel zoom and panning for exploration.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/917508fe73a5423095aa0fe520a49fa5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
