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 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

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 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 visualizes a hierarchical dataset of food categories and items, where nodes can have multiple parents, creating a non-tree structure. It displays the data as a left-to-right node-link diagram, with each item's label rendered as text and connections drawn as curved paths. The code uses D3.js v5 and the `tree`, `hierarchy`, and `linkHorizontal` APIs to lay out the graph, while a custom algorithm deduplicates repeated child nodes by ID and repositions them. The visualization is rendered as an SVG and includes pan and zoom interaction via D3's `zoom` event. The data is loaded from a JSON file and uses a transition animation to update node positions.

Fork of Fork of Fork of D3 Tree with Multiple Parents

This interactive visualization displays a hierarchical tree with multiple parent links, allowing nodes to connect across branches. Clicking a node collapses or expands its children with smooth transitions. Using D3 v5’s tree layout, linkHorizontal paths, and zoom behavior, the code renders SVG text labels and links, with node positions recalculated from a JSON dataset via Underscore utility functions.

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.

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.
