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.

AI-generated description

This is a tree diagram that used data from a 'flat' format.

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 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.

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 flat data with v4

This tree diagram visualizes hierarchical relationships from flat, parent-child data, rendering nodes and curved links in an SVG. It uses d3.stratify() to convert the flat data into a hierarchy, then applies the d3.tree() layout to position nodes. The code assigns node names via treeData.each(), draws paths for links with cubic Bézier curves, and styles circles and text for internal and leaf nodes. The example demonstrates d3 v4’s approach to handling non-nested data, with margins and dimensions set explicitly for the SVG output.

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 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.

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.

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.
