This example demonstrates seven different hierarchical layouts—traditional tree, dendrogram, circular traditional, circular dendrogram, circle packing, treemap, and icicle—using Java class data from a CSV file. Each layout is rendered as a separate SVG, with nodes and links colored by depth using `d3.scaleOrdinal` and the `d3.schemeYlGnBu` color scheme. The code uses `d3.stratify` to convert the flat CSV data into a hierarchy, then applies layout algorithms like `d3.tree`, `d3.cluster`, `d3.pack`, `d3.treemap`, and `d3.partition`. Interactive tooltips appear on mouseover, highlighting the selected node.

Tree Demo

This example visualizes the class hierarchy of Java 8 source code as a treemap, with rectangles sized by class size and colored by depth using a sequential `d3.schemeRdYlGn` scale. Hovering over a rectangle displays a tooltip via SVG text. The code uses `d3.csv` to load the data, `d3.stratify` to build the hierarchy, and `d3.treemap` to compute the layout. SVG elements are rendered with D3 v4, and custom helper functions convert polar coordinates and handle tooltip positioning.

Tree Demo

This circle-packing visualization displays the hierarchy of Java classes and packages from a CSV file, with each circle representing a class and its size corresponding to its value. The color of each circle indicates its depth within the tree, ranging from green at the root to yellow at the deepest levels. Built with D3 v4, the code uses `d3.stratify()` to build the hierarchy, `d3.pack()` for the circle layout, and custom tooltip functions to display class names on hover.

Layout Test

This example demonstrates a hierarchical tree layout rendered as an SVG visualization, with data representing a page structure of components and partials. The tree uses d3.tree and d3.hierarchy to compute node positions, while d3.linkHorizontal draws curved paths between parent and child nodes. The visualization supports pan and zoom through d3.zoom, with the zoom transform applied to a group element containing the rendered tree. A data store module supplies the hierarchical data, and the code includes a typo where circles are appended using the incorrect tag name instead of “circle.”

Tree diagram from csv using v7

This example shows a hierarchical tree diagram built from a CSV dataset, using D3.js v7. The diagram visualizes parent-child relationships, with nodes representing items like "Top Level" and "Level 2: A," connected by curved links. It uses the `d3.tree` layout, `d3.stratify` to convert flat CSV data into a hierarchy, and `d3.hierarchy` to map the structure. The SVG output positions nodes and draws the tree with circles and text labels, styled via CSS.

Tree diagram with styling in v7

This tree diagram example, built with d3.js v7, displays hierarchical data in a classic node-and-link layout using SVG rendering. The visualization shows a root node with two children, where links use colored strokes based on each node's `level` property, and circles vary in size and fill according to the `value` and `type` data fields. The code applies custom CSS styling for node circles, text, and link paths, while using the `d3.tree()` layout and `d3.hierarchy()` API to compute positions and parent-child relationships.

Tree diagram using flat data with v7

This example shows a tree diagram with five nodes arranged in a parent-child hierarchy, rendered as circles and labeled text connected by curved links in an SVG. The diagram is built from flat data—an array of objects with `name` and `parent` properties—which is converted into a nested hierarchy using `d3.stratify()`. The layout is computed with `d3.tree()` and `d3.hierarchy()`, while SVG paths and groups are appended manually. It uses D3.js version 7 and is adapted from the D3 Tips and Tricks book.

Tree Example

This interactive tree diagram displays the hierarchical structure of a dataset, with nodes and links rendered using SVG and animated transitions. The visualization uses D3.js version 3, with the `d3.layout.tree` for layout and `d3.svg.diagonal` for curved links. Clicking nodes expands or collapses their children, with smooth transitions achieved through `transition.attr`. The static data is embedded in the code, and the example also includes a separate CSV file for population data, though it is not referenced in the visualization.

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.
