This example shows a hierarchical tree diagram that loads its structure from an external JSON file. The code uses d3.json to fetch `treeData.json`, then constructs a hierarchy with `d3.hierarchy` and lays out the nodes with `d3.tree`. It renders the tree as an SVG with circles for nodes, text labels, and curved path links, using CSS classes to differentiate internal nodes from leaf nodes. The layout is sized with fixed margins and dimensions, and the JSON data contains a top-level node with nested children.

AI-generated description

This is a tree diagram that loads the data for the tree from an external JSON file.

This is designed to be used as part of documenting an update to the book D3 Tips and Tricks to version 7 of d3.js.

Tree diagram loading external json with v6

This example shows a hierarchical tree diagram rendered as an SVG, with nodes and curved links connecting parent and child elements. It loads data from an external JSON file using `d3.json` and assigns it to a hierarchy with `d3.hierarchy`. The layout is computed using `d3.tree`, and the diagram maps each node to a circle with a text label. The data source is a simple three-level JSON structure, and the visualization uses D3 v6’s promise-based loading and the `d3.tree` layout for positioning.

Tree diagram loading external json with v5

This example shows a tree diagram that visualizes hierarchical data loaded from an external JSON file. The diagram uses a horizontal layout where parent nodes appear on the left and child nodes extend to the right, with circular markers and text labels for each node. The visualization is rendered as an SVG, built with d3.js v5, using the `d3.tree()` layout algorithm, `d3.hierarchy()` for structuring parent-child relationships, and `d3.json()` for asynchronous data loading. The data itself is a simple family tree with a top-level node, two second-level nodes, and two leaf nodes.

Tree diagram loading external json with v4

This tree diagram visualizes hierarchical data loaded from an external JSON file, using d3.v4’s `d3.tree` layout and `d3.hierarchy` to define parent-child relationships. It renders an SVG with curved link paths and circular node markers, with text labels positioned based on whether a node has children. The code demonstrates the v4 syntax for loading external data via `d3.json` and appending nodes and links to a group element, based on a horizontal tree layout example.

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 diagram using symbols for nodes in v7

A tree diagram displays hierarchical data with nodes rendered as symbols, where each symbol’s shape and size depend on the node’s value. Links between nodes are drawn as curved paths. Built with D3 v7, the code uses `d3.hierarchy`, `d3.tree`, and `d3.symbol` to generate SVG paths, with node colors set from the embedded JSON data. The example is part of the author’s update to the book “D3 Tips and Tricks.”

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 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.
