A radial tree of life visualization displays the evolutionary relationships among hundreds of species. The circular layout uses a d3.cluster layout, with branch lengths shown as radial distances. Gray line extensions connect leaf labels to the tree, and hovering over a label highlights the path to the root. A checkbox toggles between constant and variable branch lengths using d3 transitions. The code parses Newick data with a custom parser and uses d3.hierarchy and d3.scaleOrdinal for coloring major taxonomic groups.

AI-generated description

A re-implementation of Jason Davies’ Phylogenetic Tree of Life, with faded gray lines to connect the leaf nodes of the tree to their corresponding labels inspired by a figure from Nature.

This implementation modifies the depth of interior nodes in a cluster layout to show branch lengths. Toggle the checkbox in the top-left corner to show or hide branch lengths, and mouseover a label to highlight its path to the root.

Tree of Life

A phylogenetic tree visualization presents the evolutionary relationships among organisms, arranged radially with colored branches distinguishing major domains such as Bacteria, Eukaryota, and Archaea. The interactive chart allows users to toggle branch length display with a smooth animated transition. Built with D3.js, it uses hierarchical clustering to position nodes, SVG rendering for scalable graphics, and transition animations to update paths smoothly. Mouseover interactions highlight the lineage from a leaf back to the root. The data originates from a Newick-format phylogenetic tree file.

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 Radial Layout

This radial tree layout visualizes a family hierarchy, showing Mike and Marcia’s children and pets branching outward from a central root. The example demonstrates how d3.layout.tree creates a circular arrangement, with links drawn as diagonals using d3.svg.diagonal’s projection function to convert angle and radius into Cartesian coordinates. Node positions are translated to the computed radial points, while text labels rotate to maintain readability. The data comes from a local JSON file, and the visualization renders in SVG.

Tree chart

This interactive SVG tree chart displays a family lineage, using a hierarchical node-and-link diagram to show generational relationships from a single ancestor. The chart is generated with the D3.js library version 3.5.17, employing its layout tree and diagonal projection APIs to position nodes. Clicking on a node triggers an animated expansion or collapse of its children, with a 750-millisecond transition. Node circles are cyan with dark borders, and connecting links are coral, all set against a teal background. The data is hardcoded as a JavaScript array of family member names and parent-child links.

RADIAL TREE

This radial tree visualization displays a hierarchical dataset, such as a world geography or an engineering part structure, with nodes arranged in a circular layout. The code uses the D3.js v4 library, specifically the `cluster()`, `hierarchy()`, and `zoom()` APIs, along with SVG rendering. The visualization shows how the hierarchy branches outward from the root, with text labels positioned and rotated based on depth and angle. It also includes panning and zooming interaction to explore the tree structure, with the data loaded from a JSON file.

Radial Tidy Tree

This radial tidy tree visualizes the hierarchical structure of the Flare class hierarchy, with nodes arranged in concentric rings around a central root. The visualization uses the Reingold-Tilford algorithm via D3’s `d3.tree` layout, with node depth mapped to radial distance and angular position based on the branch order. The code loads CSV data from a file, processes it with `d3.stratify`, and renders SVG paths and circles using `d3.linkRadial`. Leaf and internal nodes are visually distinguished by circle fill color, and text labels are rotated to follow the radial layout, with positions and anchors adjusted based on the node’s angle and whether it has children.

RADIAL TREE 2

A radial tree visualization displays a hierarchical dataset as curved links radiating from a central root node, with leaf nodes positioned along the outer circumference. The code uses D3 v4's `d3.tree()` layout with a radial size, `d3.stratify()` to parse hierarchical CSV data, and `d3.linkRadial()` to generate the bezier paths. SVG circles mark nodes, while panning and zooming are enabled via the `d3.zoom()` API. The flare.csv dataset provides the hierarchy, and the rendering is entirely SVG-based with light blue translucent links.

RADIAL TREE 2

This radial tree visualization displays a hierarchical dataset from a CSV file, using a circular layout where branches extend from a central root. The visualization supports panning and zooming interaction, allowing users to explore the hierarchy. Built with D3 v4, the code uses `d3.stratify`, `d3.tree`, `d3.linkRadial`, and `d3.csv` to process and render the data as an SVG. Nodes are drawn as circles with text labels, and links are rendered as curved paths with light blue strokes. The tree is positioned within a large SVG canvas, with labels rotated to follow the radial structure.
