Collapsible Tree Version 3

Collapsible Tree Example

This example shows a static tree diagram generated from flat, parent-child data, with nodes and links rendered as SVG circles and paths. The code converts the flat data into a hierarchical tree structure using `d3.layout.tree` and draws it with `d3.svg.diagonal` for the curved links. It relies on the D3.js library (version 3.5.17) and uses standard SVG elements like `circle`, `text`, and `path` for visualization. The diagram is fixed-depth, with no interactive collapse or update behavior.

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 Version 1

This interactive collapsible tree visualizes a hierarchical dataset of software modules, showing parent-child relationships that expand and collapse when nodes are clicked. The tree uses d3.tree for layout, d3.linkHorizontal for curved connecting paths, and d3.zoom for panning and scaling. Nodes and links transition smoothly over 250 milliseconds via d3 transitions, with node colors distinguishing leaf nodes from branches. Data comes from the flare-2.json file, which contains nested name and value properties.

Collapsible Tree Example

This example shows a collapsible tree diagram with a horizontal orientation, displaying hierarchical data with parent and child nodes connected by curved links. The tree layout is computed using `d3.layout.tree`, and links are drawn as SVG paths using `d3.svg.diagonal` with a custom projection that swaps x and y coordinates to achieve the horizontal layout. Nodes are rendered as circles with text labels, and the code uses D3 version 3.5.17, loading the library from a CDN. The data is hardcoded as a JavaScript array with nested objects representing the tree structure.

Collapsible Tree Example

This collapsible tree diagram displays hierarchical data from a CSV file, with nodes positioned by depth and connected by curved links. The visualization loads flat data from `treedata.csv` and converts it into a tree structure using a name-to-parent mapping. Rendered with SVG, it employs the `d3.layout.tree` and `d3.svg.diagonal` APIs from d3.v3 to compute node positions and draw paths. Each node appears as a white circle with a steelblue stroke, labeled with its name, while the layout normalizes node depths to 180 pixels per level.

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 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 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()`.
