{"version":"1.0","type":"rich","title":"Fork of D3 Tree with Multiple Parents","description":"A tree diagram diverges from typical hierarchies by allowing shared child nodes to have multiple parents. The code uses `d3.tree` and `d3.hierarchy` to layout the graph, then deduplicates nodes by ID with underscore.js, and recalculates positions based on depth. Links are drawn with `d3.linkHorizontal`, while labels render as SVG text. The visualization also includes zooming via `d3.zoom` and smooth animated transitions for node updates, with data loaded from a JSON file containing two top-level topics that reference overlapping concepts.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7f93f34918ad4cff97ada7425fed3601?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
