This example shows a D3 tree layout with multiple parent nodes, where shared child nodes like "Supply and demand" and "Foreign worker" appear under both "Government of the United States" and "Stock market." The visualization deduplicates nodes by ID using Underscore.js’s `_.uniq` and remaps links to the unique targets. It uses `d3.tree`, `d3.hierarchy`, and `d3.linkHorizontal` for layout and path generation, with SVG text labels and interactive zoom and transition animations applied via `d3.zoom` and `transition`. Data is loaded from a local JSON file.

Fork of D3 Tree with Multiple Parents

This example visualizes a tree diagram with multiple parent nodes, showing how shared child concepts like "Supply and demand" and "Laborer" branch from both "Stock market" and "Government of the United States." The layout removes duplicate nodes by ID and recalculates positions based on depth, with links filtered to exclude the synthetic root. Built with D3 v5, the code uses `d3.tree`, `d3.hierarchy`, `d3.linkHorizontal`, and a `zoom` event to handle interactive panning and scaling. SVG text elements display labels with a Playfair Display font, and the animation uses `transition` to smoothly update node positions. Data comes from a local JSON file.

Fork of D3 Tree with Multiple Parents

This example shows a tree diagram where nodes can have multiple parents, allowing shared entities like "Supply and demand" and "Foreign worker" to branch from both "Government of the United States" and "Stock market." The code uses d3.tree and d3.hierarchy to lay out the hierarchical structure, with d3.linkHorizontal drawing curved links between nodes. The node positions are recalculated after duplicate nodes are removed using Underscore.js, while d3.zoom enables panning and zooming of the SVG rendering. Links and nodes transition smoothly to their updated positions, with the most recently selected parent branch highlighted in steelblue.

Fork of D3 Tree with Multiple Parents

This example adapts D3’s hierarchical tree layout to visualize a directed graph with multiple parents, showing how shared child nodes like “Supply and demand” branch from two distinct roots. It uses `d3.tree`, `d3.hierarchy`, and `d3.linkHorizontal` to compute positions, then deduplicates nodes with underscore.js and manually recalculates x/y coordinates to handle overlapping descendants. SVG paths and text elements render the links and labels, with `d3.zoom` enabling pan and zoom. The source data is a small JSON array of government and market concepts, and the view animates between states using D3 transitions.

Fork of D3 Tree with Multiple Parents

This example demonstrates a D3.js tree diagram where multiple parent nodes can share the same child nodes, creating a directed acyclic graph rather than a strict hierarchy. It visualizes data where the Government of the United States and the Stock market both connect to common concepts like Supply and demand and Foreign worker. The code uses d3.hierarchy, d3.tree, and d3.linkHorizontal to render SVG links, with underscore.js to deduplicate nodes by ID and manually recalculate x/y positions. Pan-zoom and transitions animate node movement, with a YouTube video embedded for context.

D3 Tree with Multiple Parents

This example visualizes a D3 tree layout with multiple parents, allowing nodes to be shared between different branches of a hierarchical structure. The graph displays data from a JSON file, with nodes representing concepts like "Government of the United States" and "Stock market" linking to common children such as "Supply and demand" and "Foreign worker." The code uses `d3.tree`, `d3.hierarchy`, and `d3.linkHorizontal` to generate the layout, while underscore.js handles deduplication of nodes by ID and recalculation of their positions. SVG paths and text elements render the links and labels, with zoom and transition animations applied throughout.

Fork of D3 Tree with Multiple Parents

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.

Fork of D3 Tree with Multiple Parents

This example visualizes a hierarchical tree with multiple parent relationships, using a custom dataset of interconnected topics like “Government of the United States” and “Market” that share children such as “Supply and demand.” The layout positions nodes by depth and re-calculates x-coordinates for unique nodes using `_.uniq`, while links are redrawn with `d3.linkHorizontal`. Built with D3 v5, it renders as SVG text nodes and animated paths, supports zooming via `d3.zoom`, and loads data from a JSON file.

Fork of D3 Tree with Multiple Parents

This example displays a tree diagram with multiple parent nodes, using custom data that maps topics like "Government" and "Stock market" to shared children. It builds the hierarchy with `d3.hierarchy`, applies a `d3.tree` layout, and renders links as horizontal paths via `linkHorizontal`. The code uses `_.uniq` from Underscore to deduplicate nodes, then manually recalculates x and y positions so shared children appear once. Interactive zooming via `d3.zoom` and animated transitions on node positions and opacity are included, with SVG text elements showing labels.
