Forked from D3.js collapsible tree with boxes

This example renders a collapsible tree graph in SVG using D3.js v3, with each node representing a person in a nested JSON data structure. Colored rectangles distinguish node types, and links connect parent to child nodes. The tree layout dynamically recalculates its dimensions based on node depth and width, and supports zoom and drag navigation via `d3.behavior.zoom`. Clicking a node expands or collapses its children with a smooth 750-millisecond transition, while tooltips and drop shadows enhance interactivity.

Tree Example

This interactive tree diagram displays hierarchical data with collapsible nodes. The visualization uses the D3.js library (version 3.5.17) with a static JSON dataset containing a root node and its descendants. The code employs `d3.layout.tree` for layout computation and `d3.svg.diagonal` for link rendering. Users can click nodes to expand or collapse subtrees, triggering smooth animated transitions via D3's `.transition()` method. The SVG rendering includes styled circles and text labels, with nodes colored steelblue or lightsteelblue depending on collapsed state.

Tree Example

This example shows an interactive tree diagram built with D3.js, where clicking a node collapses or expands its children with smooth animated transitions. The data is a hardcoded JSON structure representing a family hierarchy, with names like Roshan and Nimmat. The code uses `d3.layout.tree` to compute node positions and `d3.svg.diagonal` to draw curved links between parent and child nodes. Node and link elements are rendered as SVG circles, text, and paths, with transitions handled by D3's `transition` API.

D3.js collapsible tree with boxes

This example shows a collapsible tree diagram where each node is rendered as a labeled box, with child nodes expandable or collapsible by clicking. It visualizes hierarchical JSON data representing nodes with types, versions, and link directions. The tree uses D3.js v3 layout and SVG rendering, with zoom and drag support via `d3.behavior.zoom`. Nodes are color-coded by type, and the layout dynamically recalculates height and width based on the tree’s depth and breadth. Animated transitions smooth node repositioning during updates.

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.

Tree

This interactive tree diagram visualizes a hierarchical dataset, displaying nodes as colored boxes connected by labeled links with directional arrows. The layout renders synchronously in SVG and supports zooming and dragging via `d3.behavior.zoom`. Node colors map to `type` fields, and tooltips appear on hover, while link direction (SYNC or ASYN) is shown through arrow markers. Data loads from JSON using `d3.json`, and the layout uses `d3.layout.tree` with a `breadthFirstTraversal` to adjust SVG dimensions dynamically.

D3.js collapsible tree with boxes

This example presents a collapsible tree visualization generated from a JSON data structure, using D3.js v3. The tree is rendered as a series of connected boxes, each representing a node, and users can click on nodes to expand or collapse their children. The layout is computed with `d3.layout.tree`, and the visualization includes interactive zooming and panning through `d3.behavior.zoom`. Node colors are assigned based on their depth in the tree, and tooltips provide additional details. The entire scene is drawn as an SVG with animated transitions.

Fork of D3.js collapsible tree with boxes

This example visualizes a hierarchical dataset as a collapsible tree, where nodes are rendered as colored boxes and labeled with names. Clicking a node expands or collapses its children, with smooth animated transitions. The tree is built using the `d3.layout.tree` and `d3.behavior.zoom`, and rendered as SVG. Link directions (SYNC/ASYN) and node types are encoded through edge colors and box fills, with tooltips providing additional metadata on hover.

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.
