{"version":"1.0","type":"rich","title":"Simple Tree Diagram - Vertical","description":"This example shows a vertical tree diagram with a single parent node branching into two children, one of which has a grandchild. It uses D3 v4’s `d3.hierarchy` and `d3.tree` layout to compute node positions, and renders the structure as SVG. Links are drawn as vertical paths using `d3.linkVertical`, while nodes appear as white circles with steelblue strokes and text labels. The data is hardcoded as a JavaScript object with a `name` and nested `children` array, and the diagram is centered with margins applied to the main group.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-bbb62ebadb78a0da831ab4f8d2cb410c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
