A chord diagram visualizes dependencies between classes in a software hierarchy, with arcs representing packages and ribbons showing imports between and within them. The code uses d3.chord to compute the matrix and d3.arc and d3.ribbon for rendering, with color mapping via d3.scaleOrdinal. Data comes from a JSON file listing class names and their imports, rendered as SVG. The diagram reveals circular dependencies, such as between vis.data and vis.events.

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.

Chord Diagram

A chord diagram visualizes package-level dependencies within the Flare class hierarchy, with each arc representing a package and chords showing import relationships between and within packages. The diagram groups classes by their parent package, revealing total import counts and circular dependencies such as between *vis.data* and *vis.events*. Built with D3 v3, it uses `d3.layout.chord` and `d3.svg.chord` to compute and render the matrix, with arcs drawn via `d3.svg.arc` and colors from ColorBrewer’s categorical scale. Data comes from a JSON file listing class imports.

Chord Diagram

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()`.

Chord I

A chord diagram visualizes directed relationships among four entities, with ribbons showing the magnitude of flow between groups and colored arcs representing each group’s total. The layout mirrors Circos and Martin Krzywinski’s design. Built with D3 v4, the code uses `d3.chord` to compute the chord layout, `d3.arc` for the group arcs, and `d3.ribbon` for the connecting bands. Colors come from `d3.scaleOrdinal`, and tick labels are formatted via `d3.formatPrefix`, with matrix data hardcoded in the source.

Chord

This visualization uses a chord diagram to display the pairwise relationships in a 10x10 numeric matrix, with each node representing a class from a CSV file. The diagram shows ribbons connecting the nodes, where each ribbon’s color reflects the source or target node based on which has a higher value, and its opacity is fixed at 0.5. The code loads data with `d3.csv` and `d3.json`, then uses `d3.chord` to compute the chord layout, `d3.ribbon` for the connecting paths, and `d3.arc` for the outer arcs, all rendered as SVG within a React-compatible HTML page using D3 v6.

Chord Diagram2

A chord diagram visualizes directed relationships among groups, here showing material-system connections in construction trades such as Occupants, Flooring, and Structure. Each group appears as an arc segment, with ribbons linking entities proportionally to the matrix values. The example uses D3 v5’s `d3.chord`, `d3.arc`, and `d3.ribbon` to compute and render the layout in SVG, with a custom `groupTicks` function and a pre-defined color scale. Data is embedded as a JavaScript object, and the diagram is rotated 75 degrees with labeled tick marks.

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`.

Chord Diagram

This chord diagram visualizes a 4x4 matrix of directed relationships, with ribbon thickness and arc sizes encoding the numeric values. The static SVG renders using `d3.chord()`, `d3.arc()`, and `d3.ribbon()` layouts, with group ticks and formatted labels generated by `d3.formatPrefix`. Categories are assigned colors via `d3.scaleOrdinal` over a custom palette. The code defines its own `groupTicks` function to position tick marks along each arc, while ribbons are filled by target-group color with a darker stroke.

Chord Layout

A chord diagram displays three groups of flows, with each group’s values (`10, 20, 30`, etc.) represented as ribbons connecting around a circle. The diagram uses d3’s `d3.chord` layout to compute chord paths and `d3.ribbon` with a fixed radius of 200 to generate the curved ribbon shapes. Static example data is loaded directly from a JavaScript array, and the SVG output is styled via CSS with light fills and strokes. The visualization renders paths inside a `<g>` element translated to center the layout.
