Forked from Fork of Fork of Fork of D3 Starter

This example displays a university department hierarchy as a vertical tree diagram, using circles for nodes and labeled edges to show parent-child relationships. It loads CSV data from a GitHub Gist via `d3.csv`, then applies `d3.stratify` to build a hierarchical root and `d3.tree` to compute the layout. The SVG output draws curved links with `path` elements and positions nodes and labels based on computed coordinates, with all styling handled through CSS. The tree’s structure is immediately visible, with text placed left or right of nodes depending on whether they have children.

This example shows a hierarchical tree of a university department structure, with colored nodes connected by curved links. The layout is computed using D3’s `d3.stratify` and `d3.tree` APIs, which organize the data into parent-child relationships and positions nodes in a tidy tree. Node positions are rendered as SVG circle and text elements, while links are drawn as cubic Bézier paths using template literals. Data is loaded remotely from a CSV file via `d3.csv`, and all rendering uses the D3 v7 library.

fork of tree

This interactive organizational chart displays a university hierarchy using a tree layout, with nodes representing colleges, departments, and academic fields connected by smooth curving links. Built with D3.js v5, the SVG visualization renders each node as a circle with text labels, using the `d3.hierarchy` and `d3.tree` APIs to compute the layout. The code applies the Playfair Display font and styles nodes, links, and text via CSS. The dataset is defined inline as a nested JavaScript object, showing a static hierarchy without interactivity.

Fork of Fork of D3 Stratify tree diagram

This example shows a hierarchical tree diagram built from CSV data using the D3 `tree()` layout and `linkHorizontal` for curved edges. The visualization renders as an SVG within a React component, with nodes and paths styled in a green color scheme. The code loads data from an inline CSV string with parent-child relationships, then applies the D3 `stratify` method to structure the data before passing it to the tree layout. The diagram spans the full width and height of the viewport, with margins applied to position the hierarchical structure.

This example shows a company employee hierarchy as a tree diagram, with nodes colored by depth: red for the root, green for level-one employees, and blue for deeper levels. Each node displays two text labels—the employee name and position—and hover states change node fill and label styling. The code uses D3 v7’s `d3.stratify` to convert flat CSV data from a GitHub Gist into a hierarchy, then lays it out with `d3.tree`. Links are drawn as SVG lines, and nodes are styled via appended circles and text elements.

Fork of Tree

This example visualizes a hierarchical dataset as a tree diagram, with nodes represented as red-stroked circles and connecting links drawn as paths. The tree layout is computed using `d3.stratify` and `d3.tree`, and the SVG rendering animates the paths and circles on load. Node labels fade in with delays based on depth, using D3 transitions. The data is hardcoded as an array of parent-child pairs, and the visualization is built with D3 v6 in a plain HTML page.

Fork of D3 Starter

This example shows a hierarchical tree of food categories, with Fruits, Vegetables, Grains, and Proteins branching into individual items. It uses d3.hierarchy and d3.tree to compute the layout, then renders links with d3.linkHorizontal and nodes as SVG circles and text labels. The data is embedded as a JavaScript object, and the visualization uses d3.v7 with an SVG rendering approach, assigning distinct colors to each category and its child nodes.

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.

Fork of React & D3 Vibecoding Starter

This example displays a three-generation family tree using a static hierarchical layout, with color-coded nodes indicating depth. It uses D3 v7’s `d3.hierarchy`, `d3.tree`, and `d3.linkHorizontal` to position and connect nodes, rendering an SVG with circles and labels. The tree is drawn from a hard-coded JavaScript object, with edge paths and node groups appended via joins. Node fill colors are mapped by depth using `d3.scaleOrdinal`, producing a simple, beginner-friendly illustration of a tree diagram.
