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.

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.

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

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

This example displays a family tree as an animated SVG diagram using D3 v6. The visualization shows a hierarchical structure of names, with parent-child connections drawn as blue lines that animate from each parent node to its child. Circles representing individuals are grey with red borders, and text labels appear with staggered timing based on depth. The code uses D3's `stratify` method to convert the flat parent-child data into a hierarchy, then applies `tree` layout and `transition` animations to animate the paths, circles, and text.

Project: Tree

This visualization displays a hierarchical tree of music genres, with individual artists attached as leaf nodes based on their deepest associated genre. The layout uses a d3.cluster tree, with artist nodes positioned at a fixed depth and colored by play count using a d3.scaleSequential with the interpolatePlasma color scheme. Data is loaded from a CSV file of Last.fm listening history and a JSON genre hierarchy. The code employs d3.hierarchy, d3.linkHorizontal, and a d3.zoom behavior for panning, rendering all elements as SVG with text labels sized by artist plays.

Fork of D3 Hierarchies - eg2

This example shows a hierarchical tree visualization of movie data, grouped by distributor and genre, with the worldwide gross revenue aggregated for each group. The root hierarchy is built using `d3.rollup` and `d3.hierarchy`, then laid out with the `d3.tree` layout. Nodes are drawn as circles, connected by lines, with labels above and leaf counts below. The code uses D3 v7 APIs including `d3.sum`, `d3.select`, and `.join` to render the SVG elements.

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.
