A tree diagram in d3.js v5 uses symbols for nodes instead of circles, with each symbol’s shape and size reflecting a numeric value from the hierarchical JSON data. The example applies `d3.tree()` layout, `d3.hierarchy()`, and `d3.symbol()` with conditional types (`d3.symbolCross` for values ≥9, `d3.symbolDiamond` otherwise). Links are drawn as cubic Bézier paths, with stroke colors set from each child’s `level` field, while node fills use the `type` field. Rendering is SVG, styled via CSS.

AI-generated description

This is a tree diagram with symbols used for nodes written with d3.js v5. It is based on the styled tree version here

This is designed to be used as part of documenting an update to the book D3 Tips and Tricks to version 5 of d3.js.

Tree diagram using symbols for nodes in v4

This tree diagram uses D3.js v4 to visualize hierarchical data with nodes represented by geometric symbols instead of traditional circles or text markers. The example loads a static JSON dataset and applies D3’s `d3.tree()` layout, with `d3.hierarchy` structuring the parent-child relationships. Link paths between nodes are styled with strokes based on each node's nested `level` property, while each node’s symbol shape and fill are determined by `d3.symbol()`—using `symbolCross` for values above nine and `symbolDiamond` below—and sized by the node's `value` attribute. The SVG rendering includes internal and leaf nodes with text labels positioned relative to each symbol.

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.

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.”

Tree diagram with styling in v5

This tree diagram shows hierarchical data with styled nodes and links. Node circles vary in radius based on a `value` field, while stroke and fill colors come from `type` and `level` properties. Links are curved paths with colors derived from the child’s `level`. The example uses d3.v5’s `d3.tree()` layout and `d3.hierarchy()` to structure the data, with SVG rendering for all elements. CSS classes style nodes and links, and text labels include leaf and internal node distinctions.

Tree diagram using images for nodes in v5

This tree diagram displays hierarchical data using images for each node, with links color-coded by the `level` property from the data. Built with D3 v5, it uses `d3.tree()` and `d3.hierarchy()` to compute the layout, then renders nodes as SVG `<image>` elements with `xlink:href` pointing to `d.data.icon`, while small labels appear beside each icon. The connector paths are drawn as cubic Bézier curves with the `.link` class, and all elements are styled via inline CSS. The data is embedded as a JSON object in the script.

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.

Tree diagram with styling in v4

This example shows a hierarchical tree diagram with styled nodes and links, where circles represent data objects using radius, stroke, and fill colors mapped from the source data. The layout is generated with d3.tree, while d3.hierarchy assigns the parent-child relationships from the inline JSON tree structure. The SVG rendering includes curved link paths between nodes, and node circles use values for radius plus type and level fields for stroke and fill styling. Text labels are positioned by horizontal anchor direction, which changes for internal versus leaf nodes.

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.
