{"version":"1.0","type":"rich","title":"Fork of D3 Tree with Multiple Parents","description":"A D3 v5 tree diagram visualizes overlapping parent-child relationships between US government and economic concepts, where multiple root nodes share common children. The layout uses a horizontal tree with custom x-y positioning after deduplicating nodes by ID, resolving shared descendants. Links are drawn with `d3.linkHorizontal`, and nodes are interactive text elements. The visualization includes zoom/pan support via `d3.zoom`, and animated transitions reposition nodes on update, with a steel-blue highlight emphasizing the currently selected root branch.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e3cdf96598e14ed09906dcf097412935?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
