{"version":"1.0","type":"rich","title":"Fork of D3 Tree with Multiple Parents","description":"This example visualizes a tree where nodes can have multiple parents, using a custom layout to represent connections between concepts like “Government of the United States” and “Stock market.” The D3 v5 code starts with a standard `tree` layout, then collapses duplicate nodes by ID and manually recalculates x/y positions to accommodate shared children. Links are drawn with `linkHorizontal`, and nodes are positioned based on depth and unique instances. The visualization includes a zoom behavior and transitions for node movement, rendering data from a JSON file into an SVG with text labels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6e54fca3fbc54abb99662d78b40ed7ed?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
