An updatable tree diagram displays hierarchical data with labeled nodes and curved links, rendered as an SVG. The code uses the d3.js library’s `d3.tree` layout and `d3.hierarchy` to compute node positions, then draws node circles and text via `d3.select` and SVG group elements. Link paths are generated with a custom `crossDiagonal` function that creates curved, cubic Bézier curves, and the tree updates by appending new nodes and links to the scene.

Hierarchy examples: Tree

This example demonstrates a node-link diagram for a small hierarchical dataset, showing both the original parent-child relationships and two manually added cross-links between a mid-level node and its grandchildren. The tree layout is computed using `d3.tree()` in D3 v6, and the visualization is rendered as an SVG with separate groups for nodes and links. Nodes appear as circles with text labels, while links are drawn as curved Bézier paths using a custom `crossDiagonal` function, which computes control points to create gentle arcs between connected nodes. The data is sourced from a static JavaScript object.

Hierarchy examples: Cluster

This example shows a hierarchical cluster layout, where a tree structure with nodes labeled A1, B1, B2, and C1–C3 is arranged into two levels of branches with straight connecting lines. The visualization uses d3.hierarchy and d3.cluster to compute node positions, then renders the result as an SVG with circles for nodes and line elements for links. The code applies a fixed size of 700 by 400 pixels to the layout, and the data is defined inline as a JavaScript object with nested `children` arrays. Node and link styling is set via external CSS classes.

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.

Simple horizontal tree diagram using v5

A simple horizontal tree diagram visualizes hierarchical data with three levels: a top-level root node, two second-level branches, and two leaf nodes. The code uses D3.js v5’s `d3.tree()`, `d3.hierarchy()`, and `d3.select()` APIs to compute the layout and render SVG paths for curved links and circles for nodes, with text labels positioned left or right based on whether a node has children. The diagram is defined by a static JavaScript object `treeData` and styled via CSS classes.

Tree diagram with styling in v4

This example shows a hierarchical tree diagram with styled nodes and links, where circles represent data objects using radius, stroke, and fill colors mapped from the source data. The layout is generated with d3.tree, while d3.hierarchy assigns the parent-child relationships from the inline JSON tree structure. The SVG rendering includes curved link paths between nodes, and node circles use values for radius plus type and level fields for stroke and fill styling. Text labels are positioned by horizontal anchor direction, which changes for internal versus leaf nodes.

Simple vertical tree diagram using v4

A simple vertical tree diagram visualizes a small hierarchical dataset with three levels, showing parent-child relationships through curved links and labeled circular nodes. It uses d3.v4’s `d3.hierarchy` and `d3.tree` APIs to compute the layout from an inline JavaScript object. The SVG rendering is styled with CSS, with internal nodes distinguished by text shadows, and the code is intended as a starting point for upgrading examples in the book *D3 Tips and Tricks* to version 4.

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.

D3.js Tree Example

This example shows a hierarchical tree layout with three levels of nodes—root, category, and subcategory—rendered as SVG shapes with distinct colors and symbols for each layer. It uses D3.js v5, loading the library via UNPKG, and applies the d3.tree layout, d3.hierarchy, d3.linkHorizontal, and d3.symbol APIs to position nodes and draw curved links. The data is hardcoded in JavaScript, and the visualization distinguishes node types using d3.scaleOrdinal for both color and shape.
