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.

d3 chord diagrams

This example shows a chord diagram generated from a 3x3 matrix of numeric values, using dark translucent ribbons to visualize connections between three groups. The code builds the visualization with D3 v7, using `d3.chord()` to compute the chord layout with sorted subgroups and angular padding, then renders each chord with `d3.ribbon()` at a fixed radius. The diagram is drawn as SVG paths inside a centered group element, with the input data provided as a static array in the script.

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.

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.

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

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 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 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 example visualizes a chord diagram showing relationships between four groups, with ribbon thickness representing the magnitude of connections between them. The code uses `d3.chord()` to compute group and link data from a hardcoded 4x4 matrix, then renders the outer arcs with `d3.arc()` and the connecting ribbons with `d3.ribbon()`. Each arc and ribbon is colored based on its source group using a predefined color array. The SVG is appended to a div, centered within a 440x440 viewport, with stroke outlines on all paths for clarity.
