This example shows a vertical family tree built with D3 v7, displaying multiple generations of a fictional family from a single root ancestor downward. It uses the `d3.stratify()` API to convert a flat list of `{child, parent}` pairs into a hierarchical structure, then lays out the nodes with the `d3.tree()` layout and renders the connecting links using `d3.linkVertical()`. Each node is represented as a blue circle with a text label, positioned via SVG transforms within a fixed `1000x900` viewBox, with the data hardcoded in the script.

Tree

A vertical family tree displays three generations of descendants from a single ancestor, with each node represented by a labeled circle. The visualization uses D3’s `d3.stratify()` to convert the flat `{child, parent}` data into a hierarchy, then applies the `d3.tree()` layout algorithm to position nodes top-down. Parent-child connections are drawn as paths using `d3.linkVertical()`, and the SVG output is rendered with the `join` API. The tree includes 36 individuals, branching into four main subfamilies.

Tree

This example presents a three-generation family tree as a static SVG visualization using D3.js v6. It shows a root "Grandparents" node branching into two parent nodes, each with two child nodes. The layout is computed with `d3.stratify()` and `d3.tree()`, while `d3.linkVertical()` draws the connecting paths. Node shapes and colors encode generation depth: squares represent the root, circles represent parents, and triangles represent children. A legend explains the mapping, and each node includes a tooltip via a `<title>` element.

tree and network

This example shows a multi-generation family tree as a compact vertical hierarchy, with nodes colored by depth to distinguish generations. The visualization loads CSV data containing child–parent relationships from a GitHub Gist, then uses `d3.stratify()` to build the hierarchy and `d3.tree()` to compute the layout. Curved links are drawn with `d3.linkVertical()`, while node circles use `d3.scaleOrdinal` to map generation depth to colors. A hover tooltip displays each person’s name and parent, rendered as SVG within a responsive viewBox.

Family Tree (

This example shows an animated family tree built with D3.js v6. It visualizes hierarchical relationships between family members using a tree layout, with nodes as circles colored by generation depth and connected by lime-green links. The data is defined as an array of child-parent pairs, processed with `d3.stratify()` and `d3.tree()`. The SVG rendering animates path connections and circle radii using `transition().duration()`, and labels each node with the child name.

Family Tree

This example visualizes a family tree as a hierarchical node-link diagram. It uses D3 v5’s `d3.stratify()` to convert flat parent-child data into a tree structure, then `d3.tree()` to compute layout positions. Nodes are rendered as SVG circles colored by depth (violet, yellow, red, green), connected by curved cubic Bézier paths, with each person’s name labeled via SVG text. The code runs in a React environment but renders entirely with SVG elements, with the dataset hardcoded in the script.

Family Tree

A family tree visualization displays hierarchical parent-child relationships across four generations, with nodes colored by depth and labeled with character names. Each connection animates from a horizontal line into a diagonal link as the tree expands. The implementation uses D3 v6’s `d3.stratify()` to build the hierarchy from flat data and `d3.tree()` to compute layout positions, while SVG circles, text, and paths are rendered with transitions on `attr` for smooth node growth and link drawing.

d3.tree - A Family Tree

This example visualizes a family tree as a static hierarchical diagram, showing genealogical relationships with names, birth and death years, and locations. The graph uses the d3.tree layout to position nodes, while d3.hierarchy structures the JSON data and provides descendant and link methods. Links are drawn as elbow paths with a custom function, and each node displays three text elements for the relative information. The visualization is rendered in SVG with a clean, readable design, demonstrating how d3.v4 handles tree layouts and nested data.

Fork of HTML Starter

This example shows a three-generation family tree with colored nodes representing grandparents, parents, and children, connected by curved links. The code converts flat family data into a hierarchy using `d3.stratify`, then lays it out with `d3.tree()`. Nodes are rendered as SVG circles with name and generation labels, while links use `d3.linkVertical()` to draw the connections. A `d3.scaleOrdinal()` maps generations to distinct colors.
