This fork of the collapsible tree example displays a hierarchical organizational chart with three top-level departments, each containing management and junior-level roles. D3 v4’s tree layout positions nodes horizontally, with expandable and collapsible branches triggered by clicking circle markers. Node positions animate smoothly via `transition()` over 750 milliseconds, using diagonal path curves for links. The visualization loads role data from a local array, renders as SVG, and distinguishes collapsed nodes with a lightsteelblue fill, while text labels use the `d3.hierarchy` API to manage nesting and depth.

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`.

Fork of Collapsible Tree Version 3

This collapsible tree diagram displays hierarchical employee data, organized by department such as Operation, Technology, and HR & Admin. The visualization uses a D3 tree layout with SVG rendering and animated transitions to expand and collapse nodes on click. Built with d3.hierarchy and the d3.tree() API, the code reads hierarchical data from a JavaScript object and applies a diagonal path generator for curved links. Node circles and text labels update their positions smoothly over a 750-millisecond duration, with collapsed nodes remaining visible via a lighter blue fill.

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.

Fork of D3.js collapsible tree with boxes

This interactive visualization displays a hierarchical tree structure using collapsible rectangular nodes, with each node color-coded by type and labeled with names, versions, and codes. The tree layout is computed with `d3.layout.tree`, and nodes and links are rendered as SVG elements with smooth animated transitions on collapse and expand. The implementation uses D3.js v3 and jQuery, loading hierarchical JSON data, and includes zoom and drag capabilities via `d3.behavior.zoom`. Node colors vary by data type, and tooltips provide additional details on hover.

Fork of D3.js collapsible tree with boxes

A collapsible tree diagram displays hierarchical data as rounded rectangular nodes connected by curved links, with each node labeled by name and colored according to its type. Clicking a node collapses or expands its subtree with smooth 750-millisecond transitions. The visualization uses D3.js v7’s `d3.hierarchy` and `d3.tree` layouts to position nodes, then renders SVG elements with custom node dimensions and styling. Data is loaded from a JSON object containing node names, types, and link directions.

Fork of D3.js collapsible tree with boxes

This example visualizes a hierarchical tree structure using collapsible nodes rendered as colored boxes. Users can click nodes to expand or collapse branches, with smooth animated transitions and tooltips displaying additional metadata. The visualization is built with D3.js v3 and jQuery, using SVG for rendering and D3’s layout, zoom, and drag behaviors. Data comes from a JSON file containing nested nodes with properties like type, version, and link direction, where depth-based coloring distinguishes hierarchy levels.

Fork of D3.js collapsible tree with boxes

This interactive example shows a collapsible hierarchical tree rendered as labeled, color-coded boxes connected by links. Node types are distinguished by color, and clicking a node collapses or expands its children with animated transitions. The visualization is built with D3.js v3, using `d3.layout.tree` for layout and SVG for rendering. It incorporates zoom and drag behavior via `d3.behavior.zoom` and includes custom tooltips and arrow markers. Data is loaded from a JSON file specifying nodes, links, and metadata.

Fork of D3.js collapsible tree with boxes

This fork of a D3.js v3 collapsible tree renders hierarchical JSON data using rectangular nodes colored by type. Clicking a node expands or collapses its children with a smooth animation, while links display directions and tooltips appear on hover. The visualization supports zooming and dragging via `d3.behavior.zoom`. Node layout and depth are computed with `d3.layout.tree`, and the SVG output dynamically resizes based on tree breadth and depth, with custom styling defined in CSS classes.
