This chord diagram visualizes the import dependencies between packages in the Flare software class hierarchy, where each arc segment represents a package and the ribbons show the volume of imports between and within packages. The layout uses `d3.layout.chord` with a matrix of import counts derived from the `readme.json` data file, rendered as SVG paths via `d3.svg.chord` and `d3.svg.arc`. Package labels are rotated along the outer ring, and colors come from a `d3.scale.category20c()` categorical scale, with chord strokes darkened via `d3.rgb().darker()`.

AI-generated description

A chord diagram in D3.js, showing dependencies between classes in a software class hierarchy. Dependencies are grouped according to the source and target packages. Although this diagram does not show class-level detail visible with hierarchical edge bundling, it better reveals the total number of imports between and within packages. Note, for example, the circular dependency between vis.data and vis.events. Colors by ColorBrewer.

Hierarchical Edge Bundling

A circular dependency diagram visualizes the class hierarchy of the Flare software library, with bundles of curved links connecting classes that import one another. The radial layout positions class names around the circumference, while the hierarchical edge bundling algorithm groups related dependencies together. The implementation uses D3 v4's `d3.cluster` for tree layout, `d3.radialLine` with `d3.curveBundle` for the bundled paths, and renders text labels and paths as SVG elements. The data comes from the `flare.json` file, which records each class and its imports.

Chord Chard Diagram

This example renders a chord diagram from a small 5x5 matrix of numeric values in the `flare.js` file, with labels a–e. It uses the D3 v5 `d3.chord()` layout and `d3.ribbon()` generator to draw the chord ribbons in SVG, while `d3.arc()` creates the outer group arcs. Each chord’s fill color is derived from its source index via a `d3.scaleOrdinal` with `d3.schemeCategory10`, and ribbons have a fill opacity of 0.67. Text labels are rotated around the inner radius using computed angles. The React framework is present in the metadata, though the main rendering logic is plain D3.

This visualization displays the dependency structure of the Flare class hierarchy as a radial dendrogram. The code uses D3 v4's `d3.cluster` layout and `d3.radialLine` with a curve bundle to draw curved paths between connected classes, with node labels around the perimeter. When hovering over a class, its source and target dependencies are highlighted in red and green, respectively, with the associated links thickened. The data comes from the `flare.json` file containing class names, sizes, and imports, rendered as SVG text and paths.

Hierarchical Edge Bundling

This visualization displays the dependency structure of the Flare software package as a radial hierarchical edge bundling diagram. The circular layout positions leaf nodes along the outer ring, while curved Bézier paths bundle together to show relationships between modules. Hovering over a node highlights its outgoing dependencies in red and incoming dependants in green, drawing attention to the directional flow of the network. The implementation uses `d3.cluster` for tree layout and `d3.radialLine` with `curveBundle` for the bundled edges, loading class data from a JSON file.

This dendrogram visualization displays the Flare class hierarchy as a node-link tree diagram, with all leaf nodes aligned along the right edge and internal package nodes branching to the left. The example uses the classic Flare dataset (courtesy Jeff Heer) and employs D3's tree layout with SVG rendering. Leaf nodes are positioned at a uniform depth, creating a clean right-aligned column of class names, while curved links connect them to their parent packages. This layout makes it easy to compare hierarchical depth across different branches at a glance. The visualization is implemented with D3 v3 and uses the standard dendrogram layout algorithm.

Chord Chard Diagram

A chord diagram visualizes five nodes (a through e) with uniform connections between all pairs, except for a double-weighted link from node e to itself. The chart uses D3 v5’s `d3.chord` and `d3.ribbon` to draw the ribbons and arcs, with labels positioned using `d3.arc` and trigonometric transforms. Data comes from a static JSON matrix defined in `flare.js`, rendered as SVG within a React component, with colors assigned via `d3.scaleOrdinal` and `d3.schemeCategory10`.

Hierarchical Edge Bundling

This hierarchical edge bundling visualization maps the dependency structure of the Flare class hierarchy into a circular layout. Using D3 v4’s `d3.cluster` and `d3.radialLine` with `d3.curveBundle`, it draws bundled SVG paths that connect each class to its imports. Hovering over a node highlights incoming dependencies in green and outgoing dependents in red via CSS classes. The data comes from the bundled `flare.json` file, which lists each class and its imports.

Cluster Dendrogram

This cluster dendrogram shows the hierarchical structure of the Flare class hierarchy, with leaf nodes aligned along the right edge and internal package nodes branching to the left. The layout uses `d3.cluster()` to position nodes by tree depth, while `d3.stratify()` converts the flat CSV data (flare.csv) into a hierarchical structure. Node-link paths are drawn as cubic Bézier curves, and each node is rendered as a circle with a text label. The visualization is built with D3 v4, renders to SVG, and uses the `d3.csv` loader to ingest the dataset.
