A chord diagram visualizes the flows between data nodes, with colored ribbons connecting segments around a circular layout. The example loads a JSON file containing hierarchical data with import relationships, then maps those relationships into a matrix of source-target counts. Using D3 v3's `d3.layout.chord`, it renders SVG arcs for each group and curved paths for chords, with colors assigned by a categorical scale. The visualization is built with an inner and outer radius, showing the structure of interconnections across the dataset.

A circular chord diagram visualizes a 7x7 matrix of directed relationships among seven entities, with arc lengths and ribbon widths proportional to the values. The SVG rendering uses D3 v4's `d3.chord` layout, with `d3.arc` and `d3.ribbon` generating the shapes, and a `d3.scaleOrdinal` color palette. Ticks are labeled with names from a hardcoded array, while tick placement relies on a custom `groupTicks` function. The data is a fixed in-memory matrix, not loaded from an external file.

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 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.

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.

D3 - Chord Diagram

This chord diagram uses d3.chord and d3.ribbon to visualize a 3x3 matrix of numeric relationships as interconnected arcs. The chord generator sorts subgroups in ascending order and applies a 0.04 radian pad angle, while the ribbon generator sets a fixed radius of 200. Data is embedded directly in the JavaScript as a three-row array. The resulting SVG paths are rendered with d3.select and the join operation, which binds the chord data to path elements and assigns the ribbon path data. The styling in styles.css fills the paths with a light gray and adds a subtle stroke and opacity, creating a clean, static representation of the matrix.

A collapsible hierarchical tree diagram displays the structure of analytical customer data records, organized into nested categories such as raw and derived attributes. The visualization uses the D3.js v3 library with its tree layout and diagonal path generator to render SVG nodes and links. Clicking a node toggles its children, animating the expansion and collapse with transitions. The data is loaded from the dendogram.json file.

Untitled

This example shows a chord diagram visualizing flows between four groups, with colored ribbons representing connections and arcs along the outer ring marking each group's total. The code uses d3.chord() to compute group and chord angles from a hardcoded 4×4 matrix, then renders the result as SVG paths. d3.arc() draws the outer segments, while d3.ribbon() generates the linking bands, with fill colors derived from each ribbon's source group. The visualization is built with d3.v4 and embedded in a minimal HTML page.

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.
