A random tree grows incrementally as nodes are added to random parents, with the layout recalculated after each insertion using the Reingold-Tilford tidy algorithm via `d3.layout.tree`. Existing nodes and links transition smoothly to their new positions, while entering nodes and links first appear at the parent’s previous coordinates. The SVG animation, driven by a `setInterval` timer, stops after 500 nodes, with node and link styling defined through CSS classes and `d3.svg.diagonal` for curved edges.

AI-generated description

This example builds a random tree using the Reingold-Tilford "tidy" algorithm, as described in "Tidier Drawings of Trees" and implemented by d3.layout.tree. As each node is added to the graph, it enters from the previous position of the parent node. Thus, the existing nodes and the new node transition smoothly to their new positions. The animation stops when 500 nodes have been added to the tree.

Random Tree

A random tree grows in an animated SVG visualization as nodes are added one by one to a random parent. Using d3.layout.tree, the example applies the Reingold-Tilford tidy layout algorithm to recompute positions with each insertion, while entering nodes transition smoothly from their parent’s previous location. The code renders circles and diagonal links via d3.svg.diagonal, and stops once 500 nodes have been added.

Random Tree

This example demonstrates a random tree visualization that grows incrementally as nodes are added one by one, using the Reingold-Tilford "tidy" algorithm via d3.layout.tree. It shows how each new node enters from its parent's previous position, while existing nodes and links smoothly transition to updated layout coordinates. The animation runs every 750 milliseconds until 500 nodes populate the tree, rendering circles for nodes and curved diagonal paths for links. The code relies on d3.v3, SVG, and d3’s transition system, with data binding through selections and key functions to manage entering and updating elements.

Force-Directed Tree

A force-directed tree renders 1,000 procedurally generated nodes connected in a hierarchical link pattern, with a force simulation continuously repositioning them. The code uses `d3.forceSimulation` with charge, link, x, and y forces to drive the layout, while drawing to a Canvas 2D context. Nodes appear as small filled circles, and links are stroked lines in gray, with the entire scene offset to the canvas center. Interactive dragging is enabled via `d3.drag`, letting users pull any node and observe the layout rebalance in real time.

Red-Black Binary Tree

This example visualizes insertions into a self-balancing red-black binary tree, animating each new node as it traverses the tree and recolorings occur. The tree layout is computed with `d3.forceSimulation`, applying force-directed positioning with gravity toward parent nodes and depth-based vertical placement. The visualization renders on both SVG and Canvas, selectable via radio buttons, using `d3-quant` and `d3-canvas-transition` to share code between rendering backends. A random uniform generator supplies node values, and insertions trigger timed animations that update the tree structure incrementally.

Random Traversal IV

This example shows a tree layout applied to a recursively generated maze, producing a branching structure of connected cells. The maze is created using a randomized depth-first traversal that records edge connections, and the resulting tree is rendered as a set of black link paths. The code uses `d3.layout.tree` to compute node positions from the maze’s traversal tree, then draws each link as an SVG path with `M` and `L` commands. The visualization is built with D3 v3 and SVG, with the maze generation logic implemented in plain JavaScript.

A tree with links between branches.

This example renders a tree diagram with branches that cross-link to other nodes, revealing the underlying connections in a hierarchical dataset. The visualization uses D3.js v3 to build the tree layout and draw custom cubic Bézier curves between linked nodes, adding a visual distinction from standard hierarchical edges. The data is generated procedurally, creating a random tree structure with a specified maximum depth and child count, and then selecting random pairs of nodes to create cross-links. The animation supports regenerating the data with a button click, causing the tree and its cross-links to redraw dynamically.

Improving array to tree

A shuffled array of ten numbers becomes a binary tree, with each node displaying its value. D3's `d3.stratify` converts the flat array into hierarchical data, and `d3.tree` computes the layout. The SVG renders nodes as red-bordered circles connected by black paths. A transition animates the text labels, with a duration that increases based on node depth. The example shows repeated re-shuffling and re-rendering of the tree with each of the ten random permutations.

Fork of array to tree

This example converts a random array of numbers into a hierarchical tree structure. Using D3 v6, it applies `d3.stratify` to build the hierarchy from parent-child relationships, then `d3.tree` to compute node positions. The animation updates node text values with staggered `transition` delays based on tree depth. Red-stroked SVG circles represent nodes, and black paths connect parent and child positions. The visualization demonstrates dynamic re-rendering of tree data with smooth text transitions.
