{"version":"1.0","type":"rich","title":"Fork of D3 Tree with Multiple Parents","description":"This visualization shows a tree diagram with multiple parent nodes, where shared child nodes appear under multiple branches. The example uses a custom D3 v5 layout with `d3.tree()` and `d3.hierarchy()`, then post-processes nodes with underscore.js to deduplicate them by ID. It renders HTML tables inside `foreignObject` elements for each node, with collapsible sections triggered by clicks. Links are drawn using `d3.linkHorizontal()`, and the entire SVG supports pan and zoom via `d3.zoom()`. The data comes from a JSON file describing government and market hierarchies.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e7374c00d44b461189902986f5587264?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
