Most simple d3.js tree

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 v5

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.

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 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.

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 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 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.
