Two chord diagrams compare the visual effect of different opacity levels on inter-country migration flows. The left diagram uses the default chord opacity of 0.7, while the right applies a lower opacity of 0.2 through the `.chordOpacity()` method, making overlapping ribbons more transparent. Both are rendered as SVG using the VizJS `viz.ch()` API on top of D3 v4, with data from a hardcoded array of migration counts between five countries. Node colors are mapped per country via a custom `fill` function.

The left grpah has the default chordOpacity of 0.7 and the right has 0.2.

Viz - chord - chordOpacity

This example visualizes immigration flows between five countries using a chord diagram rendered in SVG. The chord layout, generated by the Viz.js library, uses the `chordOpacity(0.2)` setting to make the ribbons semi-transparent, revealing overlapping relationships. The data is a hardcoded array of source-target-value triplets, with the diagram centered at a fixed transform. The code relies on d3.v4 for the SVG structure and Viz.js’s chord API to compute and draw the arcs and connecting bands, though no custom D3 scales or axes are implemented.

Chord I

Two side-by-side chord diagrams visualize migration flows among five countries: one for emigration and one for immigration. The diagrams use the VizJS library’s chord layout, invoked via `viz.ch()`, with D3 v4 for SVG rendering. Ribbon widths encode flow magnitudes, which are formatted as thousands with `d3.format`, and group arcs are colored by country using a custom fill function. The data is a hardcoded array of origin–destination pairs, and nodes are reordered with a custom sort function.

Viz - chord - innerRadius

This example visualizes international migration flows between five countries using a chord diagram. The chart arranges the countries around a circular layout, with curved ribbons connecting source and target nations, where ribbon thickness encodes the volume of people moving between them. The inner radius of the chord layout is set to 130 pixels, creating a hollow center. It uses the Viz.js library’s `viz.chord()` function, which is called on a D3 v4 selection, while the data is provided as an array of source-target-value tuples and rendered as an SVG.

Viz - chord - default

This example shows international migration flows using a chord diagram, where each arc represents the volume of movement between two countries and the connecting ribbons visualize the directional trade of people. The diagram uses `viz.chord()` from the Viz.js library, which is called on a D3 v4 selection, with data passed as a source-target-value matrix. The chart renders as an SVG inside a single `<g>` element, and the underlying data is a hardcoded array of country pairs.

Viz - chord - fill

This example visualizes migration or trade flows between five countries using a chord diagram, with each arc and ribbon colored by the source country. The data is a hardcoded array of [source, target, value] triples, and the chart is built with the viz.js library’s `viz.chord()` function, configured by a `.fill()` accessor that maps country names to colors. The diagram is rendered into an SVG `<g>` element using a standard D3 v4 selection and call operation, with the chord layout centered via a translate transform.

Chord - source, target, value

Two chord diagrams display directional flows between five countries using data from a static array of source, target, and value triples. The left diagram uses default accessors (`d=>d[0]`, `d=>d[1]`, `d=>d[2]`), while the right overrides them with `viz.ch().source`, `.target`, and `.value` functions, doubling the value and reversing source/target. Rendered as SVG via d3.v4 and VizJS, each diagram uses a custom `fill` function mapping country names to colors, and both are placed side-by-side in a single SVG canvas.

Chord - padding

Two chord diagrams side by side compare the effect of padding on arc segmentation, with the left using a default small gap and the right displaying a zero-padding continuous ribbon. The diagrams encode trade flows between the US, Canada, UK, China, and India using SVG paths. Built with the VizJS `viz.ch()` API on top of D3 v4, each diagram applies a custom `fill` color per country and uses explicit `data` arrays. The example highlights how the `.padding()` method adjusts visual separation between boundary arcs.

Viz - chord - duration

A chord diagram visualizes directional flows among four countries—US, Canada, UK, China, and India—using matrix-like value pairs. The chart uses `viz.chord()` from the vizjs library to render an animated SVG, with a 1000-millisecond duration for the transition. Data is hardcoded as arrays of [source, target, value] tuples, and the diagram is drawn inside an SVG `<g>` element. The rendering leverages D3 v4 to manage the SVG structure and transitions, showing the magnitude of trade or migration between each pair.
