This example visualizes plant generation data and a custom tree structure using D3.js version 3’s `d3.layout.tree`, `d3.svg.diagonal`, and SVG rendering with animated transitions. It shows hierarchical relationships through collapsible nodes, where clicking toggles child visibility, and includes an additional link connecting two non-parent-child nodes via a custom `additionalLinks` array. Nodes are rendered as colored rectangles with text labels, while paths represent parent-child connections. The code computes layout positions based on depth and applies 750-millisecond transitions to smoothly update node and link positions during collapse and expansion.

Tree Example

This tree diagram shows a hierarchical dataset with collapsible nodes, where clicking a parent node hides or reveals its children with animated transitions. The visualization uses D3.js v3’s `d3.layout.tree` to compute node positions and `d3.svg.diagonal` for curved links, rendered as SVG elements. Node and link styling are defined via CSS classes, and the `update` function handles enter, update, and exit transitions with a 750ms duration. The static sample data includes a top-level node with two second-level branches, demonstrating the interactive expand/collapse behavior.

D3.js collapsible tree with boxes

This example shows a collapsible tree layout where each node is rendered as a labeled box, with hierarchical relationships indicated by curved links and directional arrows. The visualization uses D3.js v3’s `d3.layout.tree` to compute node positions and supports interactive collapsing/expanding of branches, along with zoom and drag navigation. Node colors correspond to a `type` field in the accompanying JSON data, and tooltips appear on hover to reveal additional metadata. The SVG output animates layout transitions using D3’s built-in transition system.

Simple Collapsible Tree

This interactive visualization displays a hierarchical tree that expands and collapses when nodes are clicked. The tree uses a horizontal layout with circular nodes and text labels, and collapsible branches animate smoothly via transitions. The code employs D3 v3’s `d3.layout.tree` for positioning and `d3.svg.diagonal` for link paths, with sample data from a manual tree structure containing "Top Level" and dummy child nodes. SVG elements provide the rendering, and animations use `transition().duration()` to update node positions on interaction.

Tree Example

This example displays an animated, collapsible tree diagram representing a three-level family hierarchy, with nodes showing names and links connecting parents to children. Clicking a node toggles the visibility of its subtree, smoothly transitioning the layout as branches expand and collapse. Built with D3.js version 3.5.17, the visualization uses the `d3.layout.tree` and `d3.svg.diagonal` APIs to compute the node positions and draw curved link paths, while SVG transitions animate the changes over 750 milliseconds. The data is hardcoded as a nested JavaScript array in the HTML file.

Tree Example

This example shows a collapsible tree diagram built with D3.js, displaying hierarchical data with nodes for “Grand parent,” “Parent A,” and “Parent B.” Clicking a node toggles its children, animating the layout transitions over 750 milliseconds. The visualization uses `d3.layout.tree` for positioning, `d3.svg.diagonal` for curved links, and SVG circles and text for nodes. Data is hardcoded in a JavaScript array, rendered with React-style CSS classes and pointer cursor interactions.

D3.js collapsible tree with boxes

This example visualizes a hierarchical tree structure using D3.js, where each node is rendered as a colored rectangle containing text and interactive tooltips. The visualization displays a collapsible tree that users can expand and collapse by clicking on nodes, with SVG graphics and smooth animations for transitions. The code uses D3.js v3’s `d3.layout.tree` and `d3.behavior.zoom` to manage layout and pan/zoom interactions, along with jQuery for event handling. Node colors correspond to different `type` values in the JSON data, and links between nodes are styled with arrows, with tooltips appearing on hover.

D3.js bidirectional collapsible horizontal tree with rectangles

This example presents a bidirectional, collapsible horizontal tree layout using D3.js v3 and SVG rendering. It visualizes hierarchical data from a JSON file, with nodes displayed as rectangles that expand or collapse on click. The tree supports nodes positioned on both left and right sides of the root, with links and arrows drawn between them. Animated transitions adjust node positions when branches are toggled, while mouse interactions trigger the collapse and expansion behavior.

Collapsible Tree Version 2

This collapsible tree visualization shows hierarchical data from a JSON file, where nodes can be clicked to expand or collapse their children. The tree layout is computed using the `d3.tree()` layout algorithm with horizontal links drawn via `d3.linkHorizontal()`. The visualization uses D3 v6 and SVG rendering, with smooth animated transitions (250ms or 2500ms with Alt key) applied to node positions and the viewBox. Clicking a node toggles its children and also collapses any other nodes with the same name, with the tree recompiled via `d3.hierarchy()`.
