This example visualizes a hierarchical tree of physics topics, showing the breakdown from general categories like Classic and Modern Physics down to specific subfields. A static, non-interactive layout renders the data as a series of linked nodes, with each link’s color corresponding to the `level` property of the descendant node. The visualization is built using the D3.js v6 library, employing the `d3.tree()` layout algorithm on hierarchical data and using SVG paths for the links. The tree data is embedded directly in the source code as a JavaScript object.

Tree

This example visualizes a hierarchical tree structure using a force-directed layout, rendering nodes and links as the graph settles into equilibrium. The React component employs the D3.js library’s `forceSimulation` and `forceLink` APIs to compute node positions and edge forces, while SVG circles and lines display the resulting network. The visualization demonstrates how D3’s data-binding updates the DOM dynamically during simulation ticks, offering an interactive view of parent-child relationships within the dataset.

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

This example shows a horizontal tree diagram of technology domains, with three levels of depth branching from a root "Technology" node into categories like Programming Languages, Web Technologies, and Data & AI, and further into specific tools and languages. The visualization uses D3.js v7 with the `d3.hierarchy` and `d3.tree` layout APIs to compute node positions, and `d3.linkHorizontal` to draw smooth curved links between parent and child nodes. The SVG rendering distinguishes node hierarchy levels through color-coded fills: orange for the root, blue for first-level children, and green for second-level nodes, with each leaf labeled in small text.

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

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.

tree

This tree visualization shows the hierarchical structure of academic fields, from a root "Science" node down to subfields and individual topics. The layout is generated by d3.hierarchy and d3.tree, with SVG paths representing links between nodes, styled with stroke colors. Node types (root, major, subfield, topic) are distinguished by shape—circles, rectangles, and ellipses—and color is applied per major scientific branch. The static rendering uses D3 v7 with a fixed 1600x900 pixel SVG canvas, positioning nodes with a computed tree layout rather than any animation or interaction.

Tree Visualization

This example displays a static, hierarchical tree layout with the root node "WEATHER" branching into three seasonal categories, each with three child nodes. It uses the D3.js v5 library with a `d3.tree()` layout and custom aggregation via `d3.hierarchy()` to structure the data. The visualization renders as SVG, applying distinct fill colors and geometric shapes (circles, rectangles, and ellipses) to each tree depth, with curved links drawn as SVG paths using cubic Bézier commands. Node labels are positioned dynamically based on whether they have children.

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.
