This example shows a static hierarchical tree layout rendered as SVG, with a root node branching into three categories (Animals, Vehicles, Countries) and their leaf children. It demonstrates the core D3.js v5 tree API, using `d3.hierarchy()` to structure the data, `d3.tree()` to compute node positions, and `d3.linkHorizontal()` to draw curved paths between parent and child nodes. The code explicitly sets SVG dimensions with margins, appends circles for nodes and text labels that align based on whether a node has children, and loads D3 via a CDN script tag.

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.

Simple Tree with D3.js

A simple hierarchical tree diagram visualizes a root node with three branches—Animals, Vehicles, and Countries—each leading to two leaf nodes. The code uses D3.js v6’s `d3.hierarchy` and `d3.tree` layouts to compute node positions, and renders the structure as an SVG with curved links via path elements. Nodes appear as steelblue circles, with labels added as text elements, and a custom `project` function converts the tree layout’s polar coordinates into Cartesian coordinates for placement.

Dynamic Tree with D3.js

This example shows a hierarchical dataset of animals rendered as a dynamic tree diagram using D3.js v6. The tree layout positions parent and child nodes, with links drawn as horizontal curved paths via `d3.linkHorizontal`. Leaf nodes display custom colors from the data, while internal nodes are light gray, and each node is labeled with its name. The visualization is built with SVG, using D3’s `d3.hierarchy` and `d3.tree` to compute node coordinates, and the SVG height adjusts to fit the tree’s extent.

D3 Tutorial

This example demonstrates a tree visualization using the Flare dataset, displayed as a circular layout with labeled nodes and hierarchical branches rendered in SVG. The code uses D3 v5’s `d3.hierarchy` and `d3.tree` to compute node positions, then draws links and circles with `d3.select` and SVG elements. The hierarchical structure shows parent-child relationships across categories like analytics, animate, and physics, with each leaf node’s value represented by its visual placement. The visualization is contained within a fixed 960x500 viewport.

Tree Visualization with D3.js

A tree visualization displays hierarchical animal data with D3.js, using a static dataset defined in JavaScript. The code builds an SVG-based dendrogram through `d3.tree()` and `d3.hierarchy()`, positioning nodes and links with horizontal link paths. Circles represent each animal, with text labels arranged by parent or leaf status. Interactive hover animations via `transition` enlarge circles and change their fill color, while the stylesheet controls node and link appearance.

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 Visualization

A static tree visualization renders hierarchical weather data with three seasonal branches, each containing three related weather conditions. The example demonstrates loading D3 v5 via UNPKG and importing ES6 modules. Using `d3.tree()` and `d3.hierarchy`, it computes node positions and draws curved links with cubic Bézier paths (`C` commands) between parent and child nodes. SVG circles and text labels show each node, with labels offset above or below based on whether a node has children.

D3.js Tree

This example displays a small hierarchical tree of flight classes using D3.js. The visualization separates the data into two main branches, Basic and Premium, each with two child nodes, and lays them out horizontally using the `d3.tree` and `d3.hierarchy` APIs. It renders the structure as an SVG, drawing curved links with `d3.linkHorizontal()` and adding circular nodes and text labels for each element. The tree is generated from a static, embedded JavaScript data object, with all coordinates assigned by the layout algorithm before being drawn on an 800 by 600 canvas.
