This example presents a vertical tree diagram built with d3.js v5, displaying a small parent-child dataset with nodes labeled "Top Level," "Level 2: A," and their descendants. It shows the hierarchical structure through SVG rendering, with circular nodes connected by curved paths. The code uses `d3.hierarchy` to process the nested data and `d3.tree()` to compute layout positions. Links are drawn as cubic Bézier curves via path string generation, while each node is a group containing a circle and centered text label, with internal nodes styled slightly differently from leaves.

AI-generated description

This is a simple vertical tree diagram written with d3.js v5.

This is designed to be used as a starting point for further development as part of documenting an update to the book D3 Tips and Tricks to version 5 of d3.js.

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 vertical tree diagram using v7

This is a simple vertical tree diagram built with d3.js v7, displaying a small hierarchical dataset with a top-level node, a branching level, and leaf nodes. It shows parent-child relationships using curved links, with internal and leaf nodes styled differently via circles and text labels. The code uses the `d3.tree()` layout and `d3.hierarchy()` to compute node positions, then renders the structure as SVG paths and groups. The data is embedded directly in the script, and the visualization is designed as a starting point for further development.

Simple vertical tree diagram using v4

A simple vertical tree diagram visualizes a small hierarchical dataset with three levels, showing parent-child relationships through curved links and labeled circular nodes. It uses d3.v4’s `d3.hierarchy` and `d3.tree` APIs to compute the layout from an inline JavaScript object. The SVG rendering is styled with CSS, with internal nodes distinguished by text shadows, and the code is intended as a starting point for upgrading examples in the book *D3 Tips and Tricks* to version 4.

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.

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.

Simple horizontal tree diagram using v7

This horizontal tree diagram shows a three-level hierarchy with a root node, two second-level nodes, and two leaf nodes, rendered as white circles with steel-blue outlines connected by curved gray links. Using d3.v7’s `d3.tree` layout and `d3.hierarchy` functions, the code positions nodes along the x-axis and assigns coordinates via the `treemap` call, then draws SVG paths for the links and SVG groups for the nodes, with labels placed to the left or right of each circle depending on whether the node has children. The data is hardcoded inline as a JSON object, and the diagram is built entirely with SVG elements appended to the page body using d3.select and `.append`.

Simple horizontal tree diagram using v4

A horizontal tree diagram shows hierarchical data with a top-level node branching into child nodes, with internal nodes labeled on the left and leaf nodes on the right. Built with d3.js v4, it uses the `d3.tree` layout and `d3.hierarchy` to compute node positions from a hard-coded JavaScript object. The SVG output renders circles for nodes, Bézier curve paths for links, and text labels styled via CSS. The code demonstrates standard d3 v4 tree-diagram APIs including `nodes.descendants()` and `node.append()`.

Tree diagram using flat data with v5

This example shows a horizontal tree diagram built with D3 v5, displaying hierarchical data from a flat array of name and parent fields. It converts the flat data into a hierarchy using `d3.stratify`, then applies the `d3.tree` layout to position nodes. The SVG rendering includes curved `path` links between nodes, with circles for nodes and labels positioned to the right for leaves and left for internal nodes. The code uses `d3.hierarchy` and D3 selections to append elements, styled with CSS for node fills and link strokes.
