This collapsible tree diagram visualizes hierarchical task data, where each node represents a task or aggregate with color-coded statuses (red for in-progress, green for complete). The visualization uses an interactive layout where any parent node can be clicked to collapse or expand the portion of the tree beneath it, with smooth animated transitions. The tree layout is rendered as an SVG using D3 v4, with nodes shown as circles colored by status and connected by curved links. The diagram dynamically resizes its height based on the number of visible nodes, and the example is built upon Mike Bostock's classic collapsible tree, updated for v4 compatibility.

AI-generated description

This is a d3.js tree diagram that incldes an interactive element as used as an example in the book D3 Tips and Tricks v4.x.

Any parent node can be clicked on to collapse the portion of the tree below it, on itself. Conversly, it can be clicked on again to regrow.

It is derived from the Mike Bostock Collapsible tree example and updated to use v4.

Kudos and thanks also go out to Soumya Ranjan for steering me in the fight direction for the diagonal solution.

Collapsible tree diagram in v4

A collapsible tree diagram presents a hierarchical dataset as an interactive node-link visualization. Users can click any parent node to collapse the subtree beneath it, hiding its descendants, and click again to expand it. The diagram uses smooth CSS transitions for animation as nodes and links move to their new positions. Built with the d3.v4 library, it uses `d3.hierarchy` and `d3.tree()` to compute the layout, and SVG elements for rendering. Node circles and connecting paths are styled with CSS, and the dataset is a simple JavaScript object with nested `children` arrays.

Collapsible Tree Version 4

This interactive collapsible tree displays hierarchical organizational data with expandable and collapsible nodes, shown as circles with labels connected by curved paths. The visualization uses D3.js v4’s tree layout and hierarchy API to position nodes, while user clicks toggle children visibility and trigger smooth 750ms transitions. Data is defined in a JavaScript object with department and role structure, rendered as SVG elements with animated enter, update, and exit states. Node styling distinguishes collapsible parent nodes with filled circles.

Collapsible tree diagram in v5

This interactive collapsible tree diagram displays a hierarchical dataset with parent nodes that can be clicked to collapse or expand their child branches. The visualization uses d3.tree() to compute node positions, d3.hierarchy() to structure the data, and SVG paths drawn with a custom diagonal function for the linking curves. Nodes are rendered as circles with text labels, and transitions animate with 750-millisecond duration when the tree structure changes. The example derives from Mike Bostock's collapsible tree and uses d3.v5's selection, transition, and merge APIs for smooth interactive updates.

Collapsible Tree Version 4

Using D3.js v3, this collapsible tree visualization presents hierarchical data from a JSON file with an animated, interactive layout. Users can click nodes to expand or collapse subtrees, with smooth transitions applied via `d3.svg.diagonal` paths and CSS styling. The tree is rendered as an SVG, while `d3.behavior.zoom` and drag-and-drop interactions enable panning and repositioning of nodes within the 900×900 pixel viewport.

Collapsible tree diagram in v6

This interactive collapsible tree diagram displays hierarchical data with clickable parent nodes that expand and collapse their child branches. Built with D3 v6, it uses `d3.hierarchy` and `d3.tree` to compute node positions, with SVG circles and text labels rendering the structure. Clicking a node triggers a smooth 750ms transition that animates nodes and diagonal link paths to their new positions, while collapsed nodes are indicated by a lightsteelblue fill and pointer cursor. The example is derived from Mike Bostock’s original collapsible tree and demonstrates node enter, update, and exit patterns with animated transitions.

Collapsible

This visualization presents a hierarchical tree structure with nodes representing data entries such as names, types, and versions, connected by links indicating synchronous or asynchronous relationships. The tree starts with a root node and expands through multiple nested child nodes, with each node styled as a colored rectangle and accompanied by tooltips. Built with D3.js (v3) and jQuery, the code uses the `d3.layout.tree` API to compute layouts, while SVG rendering and animations handle node interactions and zooming. The tree’s dimensions adjust dynamically based on its depth and width, and node colors vary by type.

Collapsible Tree Version 3

This example shows a collapsible hierarchical tree of organizational roles, with nodes representing departments and positions that can be expanded or collapsed by clicking. Using D3 v4’s `d3.tree` layout and `d3.hierarchy`, the SVG renders nodes as circles and labels connected by curved diagonal paths. Clicking a node toggles its children via a `collapse` function, while transitions animate node positions, link paths, and circle sizes over 750 milliseconds. The code uses `transition.attr` and `.duration` to smoothly update the layout, with data sourced from the `treeData` object in `data.js`.

Collapsible tree diagram in v7

This interactive tree diagram displays hierarchical data using D3 v7’s `d3.tree` layout, rendering parent-child relationships as linked circles and text labels. Clicking any parent node collapses its descendants, with smooth 750ms transitions animating the nodes and links to the clicked node’s position; clicking again expands the subtree. The SVG uses a simple dataset of labeled levels, and the code applies `d3.hierarchy` for data structuring and the `diagonal` path generator for curved links.
