{"version":"1.0","type":"rich","title":"Fork of D3 Tree with Multiple Parents","description":"This example visualizes a tree diagram where nodes can have multiple parents, shown through linked relationships between shared topics like Supply and demand and Foreign worker. The code uses D3 v5’s `tree` layout, `linkHorizontal` generator, and zoom behavior, alongside Underscore.js utilities to deduplicate nodes and reassign links after layout. Animated transitions reposition nodes using D3’s `transition` method. Data is loaded from a JSON file, rendered as SVG text labels with horizontal curved paths, and displayed on a canvas with a Playfair Display font.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/60e30ca55d01438fbc884c1edfffb0dd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
