This chord diagram visualizes flows between three groups (Jake, Sarah, and John) using a matrix of numeric values. The code uses D3 v4’s `d3.chord()` and `d3.ribbon()` to compute and draw the arcs and ribbons, with `d3.arc()` rendering the outer group segments in distinct colors. Mouseover tooltips display source and target names via a custom HTML overlay. The visualization is rendered as static SVG with no animation, though the tooltip transition is defined but not actively bound to mouse leave.

Chord Diagram Using D3 (From Graph Gallery)

A chord diagram visualizes the flow of values among four named entities—Allen, Betty, Charlie, and Dennis—using a 4x4 matrix as input. The d3.v4 library renders the diagram in SVG, with colored arcs and ribbons where each ribbon’s color matches its source group. Interactive mouseover events trigger tooltips displaying the source and target names, while a fading transition animates tooltip opacity on mouseout. The chart relies on `d3.chord()` for layout, `d3.arc` and `d3.ribbon` for geometry, and inline event handlers for tooltip display.

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.

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.

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.

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 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 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.
