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 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 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 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 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 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 adapts the D3 tree layout to support nodes with multiple parents, displaying a network of concepts such as "Government of the United States" and "Stock market" that share children like "Supply and demand." The visualization renders as a set of horizontally oriented links and text labels, with an interactive zoom feature controlled through the `d3.zoom` API. The code uses `d3.tree`, `d3.hierarchy`, and `d3.linkHorizontal` to compute and draw the graph, while `_uniq` from the Underscore library deduplicates nodes by ID, and a manual recalculation of x and y positions accounts for the merged structure. Data is loaded from a local `data.json` file, and all elements are animated and styled within an SVG canvas using the Playfair Display font.

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.
