This example displays a hierarchical tree of movie genres, from major categories like Action and Drama down to specific films such as Star Wars and Parasite. Each node is drawn as a colored circle with a text label, using a vertical layout with straight links. Built with D3 v7, it applies `d3.stratify` to construct the hierarchy from flat parent-child data and `d3.tree` to compute node positions, rendering the SVG output with unique colors from `d3.scaleOrdinal` and a custom legend.

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 Map Representation

This tree map shows a hierarchy of movie genres and example titles, with nodes represented as colored circles and connections drawn as straight lines. The visualization uses D3 v6’s `d3.stratify` to convert the flat parent-child dataset into a hierarchy and `d3.tree` to compute the layout, which aligns nodes at the same depth vertically. Circles are color-coded by generation level (root, genre, and title) and animate their radius and link paths on load via `.transition().duration()`. The SVG is rendered with a centered HTML heading and black strokes on the circles.

Treemaps

This treemap visualizes a hierarchy of movie genres and individual film titles, with color-coded circles representing different generations of the data. The dataset defines a root "MovieGroup" with subcategories like Action, Romantic, and Mythology, each containing specific movies. Built with d3.stratify and d3.tree, the visualization uses SVG elements, including animated paths for connections and circles that transition to a fixed radius. Text labels display the names of each genre and movie, rendered in bold white text over the circles.

Q2

This example displays a hierarchical tree of food categories, from the root "Food" down to specific items like "Almonds" and "Broccoli." It uses D3 v7's `d3.stratify` and `d3.tree` layouts to compute node positions, with horizontal curved links drawn via `d3.linkHorizontal`. Nodes are rendered as SVG circles colored by depth, with labels positioned to the right for leaves and left for internal nodes. A legend at the top-left explains the color mapping for each hierarchy layer.

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.

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.

Tree layout

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.

Fork of HTML Starter

This example presents a hierarchical tree visualization of movies organized by year, genre, and title. It uses D3.js version 3 to render SVG shapes—circles for years, rectangles for genres, and ellipses for individual movies—with distinct color coding per category. The tree layout is built from a static JavaScript data structure that lists movies under release years and genres. A legend in the top-right corner explains the shape-color mappings, while CSS styling controls the visual appearance, including node cursors and link colors. The visualization demonstrates a simple, static branching structure without interactive behavior.
