{"version":"1.0","type":"rich","title":"D3 onload","description":"This example shows a hierarchical cluster dendrogram rendered as an SVG, with nodes positioned by depth and leaves spread vertically. It loads tree data from a JSON file using `d3.json`, then applies `d3.layout.cluster` to compute node coordinates. Links are drawn as curved paths via `d3.svg.diagonal`, while each node appears as a circle with a text label, offset depending on whether it has children. The code uses `window.onload` to trigger the visualization, and the SVG canvas is sized 960 by 2200 pixels with a translated group for layout.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-1601164?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
