A tree diagram diverges from typical hierarchies by allowing shared child nodes to have multiple parents. The code uses `d3.tree` and `d3.hierarchy` to layout the graph, then deduplicates nodes by ID with underscore.js, and recalculates positions based on depth. Links are drawn with `d3.linkHorizontal`, while labels render as SVG text. The visualization also includes zooming via `d3.zoom` and smooth animated transitions for node updates, with data loaded from a JSON file containing two top-level topics that reference overlapping concepts.

Fork of D3 Tree with Multiple Parents

This example shows a multi-parent tree diagram where nodes can have multiple parents, using a simple dataset with overlapping children. The visualization highlights the selected node and its connections. The code uses D3 v5's `tree`, `hierarchy`, and `linkHorizontal` to create the layout, with a custom algorithm to handle duplicate node IDs by consolidating them and adjusting their positions. Links and nodes are rendered as SVG paths and text elements, with animated transitions and zooming, while underscore.js helps with unique node filtering and depth calculations.

Fork of D3 Tree with Multiple Parents

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.

Fork of D3 Tree with Multiple Parents

This block-and-line diagram, titled "Fork of D3 Tree with Multiple Parents," visualizes a hierarchical dataset where nodes can have multiple parent connections, as seen in the `data.json` structure. It demonstrates a modified D3 tree layout that de-duplicates shared descendants and recalculates positions to flatten overlapping branches. The visualization uses D3 v7 APIs including `d3.tree`, `d3.hierarchy`, and `d3.linkHorizontal`, with underscore.js for node uniqueness. Rendered as static SVG text labels with link strokes, it includes zoom and pan interactions via `d3.zoom`, though transitions and selection highlighting are only partially implemented in the code.

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.

Fork of D3 Tree with Multiple Parents

This visualization adapts a D3 tree layout to support multiple parent nodes, showing how data entries like "Supply and demand" can be shared across different top-level categories. It loads JSON data and renders an interactive, zoomable SVG diagram with animated transitions. The code uses d3.tree, d3.hierarchy, d3.linkHorizontal, and d3.zoom, while manually deduplicating nodes with underscore.js and recalculating x/y positions to handle the shared nodes. A root node is added and filtered out, and links are remapped to the visible unique targets.

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 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.

Fork of Fork of D3 Tree with Multiple Parents

This example visualizes a hierarchical tree with multiple parents, showing how nodes like "Laborer" and "Foreign worker" connect to several top-level categories. It flattens the hierarchy by deduplicating repeated nodes and manually recalculating their x- and y-positions using `_.uniq`, `_.where`, and depth-based spacing. The SVG renders horizontal links with `d3.linkHorizontal`, supports zooming via `d3.zoom`, and animates node transitions on click. Data comes from a local JSON file, and traversal uses `d3.hierarchy` and `d3.tree`. The latest top-level child is highlighted with a steel-blue stroke.
