This example visualizes the class hierarchy of Java 8 source code as a treemap, with rectangles sized by class size and colored by depth using a sequential `d3.schemeRdYlGn` scale. Hovering over a rectangle displays a tooltip via SVG text. The code uses `d3.csv` to load the data, `d3.stratify` to build the hierarchy, and `d3.treemap` to compute the layout. SVG elements are rendered with D3 v4, and custom helper functions convert polar coordinates and handle tooltip positioning.

Tree Demo

This circle-packing visualization displays the hierarchy of Java classes and packages from a CSV file, with each circle representing a class and its size corresponding to its value. The color of each circle indicates its depth within the tree, ranging from green at the root to yellow at the deepest levels. Built with D3 v4, the code uses `d3.stratify()` to build the hierarchy, `d3.pack()` for the circle layout, and custom tooltip functions to display class names on hover.

Tree Demo

This example demonstrates seven different hierarchical layouts—traditional tree, dendrogram, circular traditional, circular dendrogram, circle packing, treemap, and icicle—using Java class data from a CSV file. Each layout is rendered as a separate SVG, with nodes and links colored by depth using `d3.scaleOrdinal` and the `d3.schemeYlGnBu` color scheme. The code uses `d3.stratify` to convert the flat CSV data into a hierarchy, then applies layout algorithms like `d3.tree`, `d3.cluster`, `d3.pack`, `d3.treemap`, and `d3.partition`. Interactive tooltips appear on mouseover, highlighting the selected node.

TreeMapv2

This example visualizes a hierarchical tree structure of software model elements using a treemap layout. The graph.json data shows nested EClass objects organized by domain, with each node’s size determined by its `degree` value. D3 v3’s `d3.layout.treemap` algorithm partitions the 960×500 SVG canvas, rendering each node as a rectangle with a label, colored via the `category20c` scale. The visualization uses `d3.json` to load the data and SVG `rect` and `text` elements for output.

TreeMap Layout

This example demonstrates a treemap layout using D3 v5, displaying hierarchical data as nested rectangles sized proportionally to their values. The visualization shows four labeled nodes—three leaf nodes (C1, C2, C3) with varying values beneath a parent node (B1), alongside a sibling node (B2)—all enclosed within root A1, with padding and gaps between groups. It uses `d3.hierarchy` to structure the data and `d3.treemap` to compute the layout, rendering rectangles and text as SVG elements. The treemap applies an outer padding of 16 pixels and scales to a 400×200 pixel area, with a static dataset defined in the code.

Fork of TreeMap Layout

This example displays a treemap visualization of hierarchical data using D3 v5’s `d3.hierarchy` and `d3.treemap` layouts. The SVG renders nested rectangles sized proportionally to node values, with labels for named leaves and empty labels for internal branches. The code manually constructs the dataset in `index.js`, sums values via `root.sum`, and applies layout properties like `paddingOuter`. Rectangles and text are appended into grouped `<g>` elements, with styling from `styles.css` using royal blue fills and white strokes.

visualization9d3

A D3.js treemap displays hierarchical data as nested rectangular nodes, sized proportionally to each value. The visualization shows five course categories with descending values, using a spectral color scale for differentiation. The code embeds a static dataset directly and builds the hierarchy using `d3.hierarchy` with a sum accessor, then applies `d3.treemap` to compute the layout. Each leaf node renders as a positioned `div` element, with dimensions derived from the treemap’s computed coordinates and colors assigned via `d3.interpolateSpectral`.

TreeMap

This example visualizes a hierarchical dataset as a treemap, using rectangles sized by each node’s `degree` value and colored by its `domain` attribute to reveal the relative prominence of categories. Built with D3 v3, the code loads hierarchical JSON data and applies the `d3.layout.treemap` layout with custom padding. Node labels and background colors are assigned via D3 selections, with positions and dimensions computed by the layout and applied through inline styling. The visualization provides a compact overview of the dataset’s nested structure and degree distribution.

TreeMapping

A static SVG treemap built with plain HTML and CSS, styled with large text and a red color palette. The visualization uses nested rectangles to represent hierarchical data, with layered `<rect>` elements manually positioned via absolute coordinates. Rendered entirely through declarative SVG markup rather than D3 data joins, it serves as a basic exercise in geometric composition and color coding. The code includes D3 v7 via CDN but does not invoke any D3 APIs.
