Fork of D3 Tree with Multiple Parents

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 visualization shows a hierarchical tree structure in which multiple parent nodes can share the same child, as demonstrated by two top-level categories both linking to common descendants like “Supply and demand” and “Laborer.” It uses D3 v5’s `stratify` and `tree` layouts to convert flat JSON data into a dendrogram, rendering nodes as text labels and edges as horizontally curved `linkHorizontal` paths. The SVG canvas supports zooming via D3’s `zoom` behavior, and text styling relies on the Playfair Display font with a white shadow for readability.

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 with nodes that can have multiple parents, using data about related concepts like "Supply and demand" and "Foreign worker." The visualization repositions nodes to avoid duplication, calculating new coordinates after filtering unique nodes by ID. It uses D3's `tree` layout, `linkHorizontal` path generator, and a custom zoom interaction via the `zoom` event. The SVG text nodes and links are animated with transitions, with links colored based on a selected state.

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 Example

This example adapts the D3 tree layout to visualize hierarchical data with multiple parents, where nodes may be shared across different branches. It shows a network of interconnected categories like "Government" and "Supply and demand" organized into overlapping trees, with the last root branch highlighted in blue. The code uses d3.hierarchy and d3.tree to compute positions, then deduplicates nodes by ID using underscore.js and manually recalculates their x/y coordinates to accommodate shared descendants. Links are drawn with d3.linkHorizontal, and the SVG view supports pan-and-zoom via d3.zoom, with data loaded from a local JSON file.

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 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.
