{"version":"1.0","type":"rich","title":"Fork of Tree Example","description":"This example shows an interactive hierarchical tree diagram built with D3.js, where users can click nodes to expand or collapse their children. The visualization renders a family tree with named individuals such as Roshan, Nimmat, and Salim, using SVG circles and text labels connected by curved diagonal paths. The code uses `d3.layout.tree` to compute the layout, `d3.svg.diagonal` for the links, and transitions on node and link elements to animate position changes smoothly over 750 milliseconds. Data is embedded directly as a JavaScript object array, and each node’s color shifts to lightsteelblue when collapsed.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1bcd93a7019442cc97b86b00a47c5726?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
