{"version":"1.0","type":"rich","title":"Simple Tree Diagram - Horizontal","description":"A horizontal tree diagram displays a simple hierarchical dataset with a root \"Parent\" node leading to two children, one of which branches to a grandchild. The visualization uses D3 v4's `d3.hierarchy` and `d3.tree` layouts, rendering nodes as SVG circles and links as horizontal paths via `d3.linkHorizontal`. Node and link styling is set through CSS classes, with text labels positioned above each circle. The data is embedded directly in the code as a JavaScript object.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-efa049e8015024669f56ec634e6a7394?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
