{"version":"1.0","type":"rich","title":"Most simple d3.js tree","description":"This example shows a minimal hierarchical tree visualization of hardcoded parent-child data, with labeled circular nodes connected by curved diagonal links. The code uses `d3.layout.tree` to compute node positions and `d3.svg.diagonal` for the link paths, while rendering nodes and text as SVG circles and labels. The tree is laid out left-to-right with a 400×300 pixel canvas, and node labels alternate sides based on whether a node has children.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-1312406?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
