Vertical Tree

A vertical tree diagram displays hierarchical data with a root node at the top and child nodes branching downward. The visualization uses SVG rendering to draw curved link paths between parent and child nodes, with node positions calculated by the d3.tree layout. The implementation loads data from a JSON file using d3.json, processes it through d3.hierarchy, and draws the connection paths using the d3.linkVertical path generator. The data represents a geographic hierarchy, from continents down to individual countries.

Tree

This hierarchical tree visualization displays cartoon character relationships with color-coded labels, where node text size decreases with depth. Using D3 v5’s `tree()` layout and `linkHorizontal()` generator, it renders an SVG with curved links and zoomable panes via `zoom()`. The data comes from nested JSON, binding each node’s `id` and `color` from `d.data.data` to text elements. Font sizing scales by depth, while text shadows and the `event.transform` handler enhance readability and interaction.

Tree diagram with styling in v5

This tree diagram shows hierarchical data with styled nodes and links. Node circles vary in radius based on a `value` field, while stroke and fill colors come from `type` and `level` properties. Links are curved paths with colors derived from the child’s `level`. The example uses d3.v5’s `d3.tree()` layout and `d3.hierarchy()` to structure the data, with SVG rendering for all elements. CSS classes style nodes and links, and text labels include leaf and internal node distinctions.

Tree diagram with styling in v4

This example shows a hierarchical tree diagram with styled nodes and links, where circles represent data objects using radius, stroke, and fill colors mapped from the source data. The layout is generated with d3.tree, while d3.hierarchy assigns the parent-child relationships from the inline JSON tree structure. The SVG rendering includes curved link paths between nodes, and node circles use values for radius plus type and level fields for stroke and fill styling. Text labels are positioned by horizontal anchor direction, which changes for internal versus leaf nodes.

Data Tree

A hierarchical data tree displays the geographic structure of World, Asia, and subregions down to individual countries. D3's `tree` layout and `hierarchy` function organize the JSON data, while `linkHorizontal` generates curved path connections between parent and child nodes. The visualization uses d3.v5 with SVG rendering, featuring adjustable pan and zoom through d3's `zoom` event handler, and labels sized according to tree depth using the `text` elements.

Simple horizontal tree diagram using v7

This horizontal tree diagram shows a three-level hierarchy with a root node, two second-level nodes, and two leaf nodes, rendered as white circles with steel-blue outlines connected by curved gray links. Using d3.v7’s `d3.tree` layout and `d3.hierarchy` functions, the code positions nodes along the x-axis and assigns coordinates via the `treemap` call, then draws SVG paths for the links and SVG groups for the nodes, with labels placed to the left or right of each circle depending on whether the node has children. The data is hardcoded inline as a JSON object, and the diagram is built entirely with SVG elements appended to the page body using d3.select and `.append`.

Wiki

This tree diagram visualizes hierarchical data as a horizontally-oriented dendrogram. The visualization uses a radial, indented layout with circular node markers, curved link paths, and text labels for each entity. It colors nodes on a white-to-purple linear scale based on a group value, and includes a square legend. The implementation relies on D3 v5.5 API functions: `select`, `json`, `tree`, `hierarchy`, `linkHorizontal`, and `zoom`. Data is loaded from a JSON file, and the SVG element is resized to the full browser viewport. A tooltip, though defined, does not appear to be applied in this example.

Simple horizontal tree diagram using v5

A simple horizontal tree diagram visualizes hierarchical data with three levels: a top-level root node, two second-level branches, and two leaf nodes. The code uses D3.js v5’s `d3.tree()`, `d3.hierarchy()`, and `d3.select()` APIs to compute the layout and render SVG paths for curved links and circles for nodes, with text labels positioned left or right based on whether a node has children. The diagram is defined by a static JavaScript object `treeData` and styled via CSS classes.
