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.

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 6 of d3.js.

Tree diagram loading external json with v7

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.

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 v6

This example demonstrates a hierarchical tree diagram rendered with D3.js v6, using SVG to display nodes and curved links. The tree layout is generated via `d3.tree()` and `d3.hierarchy()`, with circle size varying according to each node’s `value` property. Node stroke and fill colors are dynamically mapped from the data’s `type` and `level` fields, while links are styled as cubic Bézier paths with per-node stroke colors. The code also applies CSS classes for internal versus leaf nodes and includes text labels with shadows for readability. The dataset is a static, nested JavaScript object representing a simple parent-child hierarchy.

Tree diagram using flat data with v6

This example shows a hierarchical tree diagram built from flat, parent-child data. It converts the flat array into a hierarchy using `d3.stratify()`, then lays out the nodes with `d3.tree()` and renders them as SVG circles and curved links. The code assigns node names via `treeData.each()` and uses `d3.hierarchy()` to supply child relationships. Data is hardcoded in the script, and styling is set through CSS classes for internal and leaf nodes. The diagram is drawn with SVG paths and text elements.

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 diagram from csv using v6

This tree diagram visualizes hierarchical data loaded from a CSV file, with nodes representing names and links showing parent-child relationships. The example uses d3.csv to load the flat data, d3.stratify to convert it into a hierarchy, and d3.tree to compute the layout. Nodes are rendered as circles with labels, while curved paths drawn via SVG path elements connect parents to children. The code also assigns CSS classes based on whether a node is internal or a leaf, adjusting text placement and styling accordingly.

Tree diagram using symbols for nodes in v6

A tree diagram displays hierarchical data with nodes as D3 symbols, where each symbol’s shape and fill color encode a numeric value and a level attribute from a fixed inline JavaScript object. Links between nodes are colored via a separate level property, and internal nodes use cross symbols while leaves use diamonds. Built with D3 v6, it employs `d3.tree`, `d3.hierarchy`, and `d3.symbol` to render an SVG layout, with node sizes scaled by the `value` field and text labels positioned based on whether a node has children.
