A basic tree structure graph displays hierarchical data as green circular nodes connected by green straight-line links. The visualization uses the D3.js v4 `d3.tree` layout to compute node positions from a JSON array loaded via `d3.json`, with the root hierarchy created by `d3.hierarchy`. Nodes and edges are rendered as SVG circles and paths, with the latter drawn using path commands from parent to child coordinates. The example focuses on the simplest possible tree layout, showing parent-child relationships without additional styling or interaction.

Tree Graph 2

This example displays a hierarchical tree diagram illustrating the structure of a natural tree, from root to leaves. It uses the D3.js v7 library to render the visualization as an SVG. The layout is computed with `d3.tree()` and `d3.hierarchy()`, while links are drawn using `d3.linkHorizontal()`. Nodes are styled with different shapes and colors based on their depth in the hierarchy: the root is a brown circle, branches are green rectangles, sub-branches are light green diamonds, and leaves are small circles.

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.

Simple horizontal tree diagram using v6

A simple horizontal tree diagram displays a small hierarchy of named nodes connected by curved links, with internal and leaf nodes distinguished by text alignment. Built with d3.js v6, it uses the `d3.tree()` layout and `d3.hierarchy()` to compute node positions from static, inline JSON data. SVG rendering places each node as a group containing a circle and label, while the links are drawn as cubic Bézier paths via the `d` attribute. The styling includes white node circles with steelblue strokes and gray links.

Tree graph

A tree visualization displays a hierarchical data structure from a JSON file, showing parent-child relationships through vertical links and labeled nodes. The graph represents an object model with classes, attributes, and methods, using D3 v5's `tree`, `hierarchy`, and `linkVertical` layouts to position elements. Interactive pan and zoom functionality is implemented via `d3.zoom`, while nodes are rendered as SVG text with `foreignObject` elements containing input fields. The visualization supports exploration of complex nested data through its expandable tree layout.

Tree

This example shows a simple hierarchical family tree with three generations, drawn in a bottom-to-top orientation using the D3.js v3 library. It demonstrates the `d3.layout.tree` layout and `d3.svg.diagonal` for rendering curved link paths, while nodes appear as circles with text labels for each person’s name. The data comes from a local `graph.json` file containing a nested “Father,” “Son,” and grandchildren structure. The SVG output is styled with minimal CSS, using a light gray border and black links, and the layout is positioned within a fixed margin and size.

Simple vertical tree diagram using v6

This simple vertical tree diagram displays hierarchical data with a root node branching into two levels, using circles for nodes and curved paths for links. The visualization is rendered as SVG with D3.js v6, using the `d3.tree()` layout and `d3.hierarchy()` to structure the hard-coded data, then appending groups and paths via `selectAll().enter()`. Node labels are offset above or below circles depending on whether they have children, and internal text includes a white shadow for readability. The code sets explicit margins and dimensions to position the tree within the viewport.

Tree graph

A tree graph displays hierarchical data as connected nodes branching from a single root. The visualization uses a force-directed layout via `d3.forceSimulation` to position nodes, with links drawn as curved paths. Nodes are rendered as circles colored by depth, and the graph updates smoothly through D3’s `transition` when re-simulated. The code loads a JSON dataset and relies on `d3.hierarchy` and `d3.tree` to compute the tree structure before applying the force simulation for final placement.

simple tree

This visualization shows a small tree diagram with circular nodes connected by vertical paths, displaying hierarchical relationships from a CSV file. The node positions and link paths are computed using d3.stratify and d3.tree APIs, then rendered as SVG paths and circles. Data is loaded from data.csv, which contains id and parent columns, and the layout is controlled by a custom separation function that sets uniform spacing between siblings. The tree is drawn on a 960 by 500 pixel canvas using D3 v4.
