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.

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.

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.

A simple bar chart displays seven static blue rectangles on an SVG canvas, with each bar’s height proportional to a value in a hardcoded JavaScript array. The bars are positioned horizontally using a fixed width of 50 pixels per bar and aligned to a baseline of 300 pixels from the top. The visualization uses D3 v4’s selection and data-join methods (`selectAll`, `data`, `enter`, `append`) to create the rectangles, setting their `x`, `y`, `width`, `height`, `fill`, and `stroke` attributes directly. No axes, labels, or interactions are included; the chart just shows the raw data values as basic shapes.

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 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.

Seven circles are plotted diagonally across a small SVG canvas. Each circle is drawn twice, with the second copy rendered in red and only for data values excluding 6, creating a simple visual comparison of data point positions. Built with D3 v4, the code uses `d3.select`, `svg.selectAll`, and `append` to generate SVG groups and circles, with coordinates computed directly from the data array values.

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.

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.
