This tree visualization shows the hierarchical structure of academic fields, from a root "Science" node down to subfields and individual topics. The layout is generated by d3.hierarchy and d3.tree, with SVG paths representing links between nodes, styled with stroke colors. Node types (root, major, subfield, topic) are distinguished by shape—circles, rectangles, and ellipses—and color is applied per major scientific branch. The static rendering uses D3 v7 with a fixed 1600x900 pixel SVG canvas, positioning nodes with a computed tree layout rather than any animation or interaction.

Tree

This example shows a hierarchical tree of medical fields and related professionals, with nodes color-coded by generation depth. The visualization uses d3.stratify() to structure the flat parent-child data, d3.tree() to compute the layout, and SVG circles, paths, and text elements for rendering. Labels appear to the right of each node, and brown cubic Bézier curves connect parents to children. The background and text styling come from the linked stylesheet.

Tree Visualization

This example visualizes a hierarchical tree structure of a university’s departments and courses using D3 v5. Thecode imports data from a local ES6 module and renders an SVG tree layout with `d3.tree()`, `d3.hierarchy()`, and custom link paths via cubic Bézier curves. Each depth level is distinguished by a different shape (circle, rectangle, ellipse) and color, while node labels are positioned above or below based on whether they have children. The visualization runs entirely in the browser with SVG rendering.

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.

Tree

A hierarchical tree diagram displays the structure of programming languages, grouped into Web, System, and Data categories. The visualization uses a static dataset defined in JavaScript. D3.js v7 with an SVG rendering approach draws the graph, employing `d3.hierarchy` and `d3.tree` to compute the layout. Nodes are represented as colored circles, color-coded by depth using `d3.scaleOrdinal` with `d3.schemeCategory10`, while links and text labels are appended via D3's data-join methods. The tree is oriented horizontally, placing parent-child connections left-to-right.

Tree

This example shows a horizontal tree diagram of technology domains, with three levels of depth branching from a root "Technology" node into categories like Programming Languages, Web Technologies, and Data & AI, and further into specific tools and languages. The visualization uses D3.js v7 with the `d3.hierarchy` and `d3.tree` layout APIs to compute node positions, and `d3.linkHorizontal` to draw smooth curved links between parent and child nodes. The SVG rendering distinguishes node hierarchy levels through color-coded fills: orange for the root, blue for first-level children, and green for second-level nodes, with each leaf labeled in small text.

Tree Visualization

This visualization presents a hierarchical tree diagram of animal categories, showing the branching structure from a root "Animals" node down to leaf species. It uses D3 v6’s `d3.hierarchy` and `d3.tree` layouts to compute positions, rendering SVG paths for links via `d3.linkHorizontal` and circles with text labels for nodes. The code colors nodes by depth (black for root, blue for internal, green for leaves) within a hardcoded dataset of mammals, birds, and reptiles.

tree

This example displays a hierarchical tree of programming languages, organizing them into compiled and interpreted categories with individual language leaves. The visualization uses d3.csv to load the data, d3.stratify to convert the flat table into a hierarchy, and d3.tree to compute the layout. Links are drawn with d3.linkHorizontal, while nodes differentiate types using shapes—circles for parent categories and diamonds for leaves—with a d3.scaleOrdinal assigning colors by depth. SVG rendering presents the final structure against a styled page background.

Course Tree

This visualization displays a hierarchical course structure as a node-link tree, with circles representing topics and connecting lines showing parent-child relationships. The tree layout is computed using d3.hierarchy and d3.tree, which positions nodes based on the nested JSON data loaded from hierarchy.json. The SVG rendering uses D3’s data join pattern, binding circle and line elements to descendant and link data respectively, with coordinates mapped to the tree’s computed x and y positions. The visualization fills the entire viewport by dynamically setting the SVG dimensions to the window size.
