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.

Dynamic Tree with D3.js

This dynamic tree visualization displays a hierarchical dataset of animals, with categories for mammals, birds, and reptiles branching into individual species. Each node is represented as a colored circle with a text label, and the tree layout positions all elements using the D3.js `d3.tree` and `d3.hierarchy` APIs. The visualization employs `d3.linkHorizontal` to generate curved links between parent and child nodes, and it renders everything as SVG elements within a React-based HTML page. The example demonstrates data-driven color coding and a responsive SVG height that adapts to the tree's computed size.

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 Visualization

This visualization presents a hierarchical tree diagram of animal categories, showing the branching structure from a root "Animals" node down to leaf species. It uses D3 v6’s `d3.hierarchy` and `d3.tree` layouts to compute positions, rendering SVG paths for links via `d3.linkHorizontal` and circles with text labels for nodes. The code colors nodes by depth (black for root, blue for internal, green for leaves) within a hardcoded dataset of mammals, birds, and reptiles.

Tree Example

This example shows an interactive family tree built with D3.js, displaying a hierarchical dataset of names and parent-child relationships. The visualization uses the `d3.layout.tree` layout to position nodes and `d3.svg.diagonal` for the curved links between them. Each node is rendered as an SVG circle with a text label, and clicking on a node toggles its children, collapsing or expanding that branch. The nodes and links animate smoothly via transitions, with colors indicating different levels in the hierarchy.

Tree layout

This example uses D3.js version 4 to render a hierarchical tree layout from CSV data. The visualization shows nodes connected by curved paths, where node labels display different data fields depending on their depth level. The tree uses `d3.tree()` to compute positions and `d3.hierarchy()` to structure the nested data. A React version is included, and an alternative HTML file demonstrates dynamic resizing with the `clientWidth` and `clientHeight` properties.

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.

D3.js Tree Example

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.

Tree Example

An interactive tree diagram displays hierarchical data with collapsible nodes, marking leaf nodes and internal nodes distinctly with text labels. Clicking a node toggles its child branches, with animated transitions repositioning nodes and links. The visualization uses D3.js 3.5.17, SVG rendering, and React via the VizHub framework, building the tree via `d3.layout.tree` and drawing curved diagonal links with `d3.svg.diagonal`.
