This example uses the D3 tree layout to display hierarchical data from a CSV file. The visualization shows a hierarchy of film records, grouped by genre and lead studio, as a node-link diagram with curved paths connecting parent and child nodes. The code uses `d3.tree`, `d3.hierarchy`, and `d3.nest` to structure the data, and renders the result as SVG with circles for nodes and labels for names at specific depths. The layout is sized to 900 by 600 units within an SVG canvas.

Tree layout

This example uses D3.js version 4 to render a hierarchical tree layout from CSV data. The visualization shows nodes connected by curved paths, where node labels display different data fields depending on their depth level. The tree uses `d3.tree()` to compute positions and `d3.hierarchy()` to structure the nested data. A React version is included, and an alternative HTML file demonstrates dynamic resizing with the `clientWidth` and `clientHeight` properties.

Films Example Data

This example visualizes a dataset of films using a hierarchical tree layout. It nests films by year and genre, then renders the hierarchy as a node-link diagram in SVG, with circles for nodes and curved paths for links. The code uses d3.nest to group data, d3.hierarchy and d3.tree to compute the layout, and custom link path generation for the curves. The data comes from a CSV file with film titles, genres, years, and other attributes.

D3 Hierarchies

This example uses the D3 library to render a hierarchical tree from a small dataset of movies, grouped by distributor and genre. It shows the distribution of films across these categories, with nodes connected by lines and labeled with category names. The visualization is built using `d3.rollup` to create a nested data structure, `d3.hierarchy` to process it, and `d3.tree` to compute the layout. Circles represent nodes, and leaf nodes display the count of movies.

Tree Layout from CSV

A tree layout visualization reads hierarchical relationships from a CSV file with source-target pairs, such as A1 to A2 and A2 to A3. Using d3.v3, it dynamically builds nodes and links from the data, rendering a tidy tree where parent and child relationships are clearly shown through straight lines and small circles. The example specifically uses d3.layout.tree for node positioning and d3.svg.diagonal for link paths, with a white-stroked node style and black link lines. The SVG output displays a simple three-node chain, illustrating how a flat two-column CSV can be transformed into a structured tree diagram.

Tree Layout

This example demonstrates a hierarchical tree layout using a cluster-based arrangement in D3 v5. It reads nested JSON data with parent-child relationships and renders the nodes as small circles connected by straight lines. The visualization uses d3.cluster to compute the layout coordinates, d3.hierarchy to structure the data, and SVG circle and line elements for drawing. The tree is positioned within the SVG canvas using a translated group element.

Movie tree

This visualization shows a hierarchical tree of movie genres and film titles, with a central “Movies” root branching into Action, Horror, Thriller, and Drama, each leading to specific movies. The D3.js `stratify()` method converts flat parent-child data into a hierarchy, which is then laid out using `d3.tree()`. SVG circles represent nodes, connected by animated paths that draw straight lines, while text labels fade in with a staggered duration based on depth. The rendering emphasizes a simple, colorful circular-node aesthetic over explicit positional encoding.

Tree 1

This example shows a hierarchical tree visualization of animal categories, with orange, sky blue, and light green circular nodes representing animals, mammals, birds, and fish. The code uses `d3.hierarchy` to structure the nested data and `d3.tree` to compute the layout positions. SVG lines connect parent-child nodes while circles and text labels display each element, rendered directly within an SVG container.

something different Movie example

This example shows a hierarchical tree visualization of scraping configurations, grouped by machine and then by name, with leaf nodes containing URL templates and xPath values. The tree layout uses `d3.layout.tree` with a custom `children` accessor that maps `d.values`, and `d3.svg.diagonal` for the curved link paths. Data is loaded from a CSV file and restructured with `d3.nest` and `rollup` to build the nested hierarchy. Interactive nodes are rendered as SVG circles and text labels, with the visualization sized at 2000 pixels wide inside an SVG canvas.
