+
+## Installing
+
+If you use npm, `npm install d3-chord`. You can also download the [latest release on GitHub](https://github.com/d3/d3-chord/releases/latest). For vanilla HTML in modern browsers, import d3-chord from Skypack:
+
+```html
+<script type="module">
+
+import {chord} from "https://cdn.skypack.dev/d3-chord@3";
+
+const c = chord();
+
+</script>
+```
+
+For legacy environments, you can load d3-chord’s UMD bundle from an npm-based CDN such as jsDelivr; a `d3` global is exported:
+
+```html
+<script src="https://cdn.jsdelivr.net/npm/d3-path@3"></script>
+<script src="https://cdn.jsdelivr.net/npm/d3-chord@3"></script>
+<script>
+
+const chord = d3.chord();
+
+</script>
+```

+<a href="#chord" name="chord">#</a> d3.<b>chord</b>() · [Source](https://github.com/d3/d3-chord/blob/master/src/chord.js)
+
+Constructs a new chord layout with the default settings.
+
+<a href="#_chord" name="_chord">#</a> <i>chord</i>(<i>matrix</i>) · [Source](https://github.com/d3/d3-chord/blob/master/src/chord.js)
+
+Computes the chord layout for the specified square *matrix* of size *n*×*n*, where the *matrix* represents the directed flow amongst a network (a complete digraph) of *n* nodes. The given *matrix* must be an array of length *n*, where each element *matrix*[*i*] is an array of *n* numbers, where each *matrix*[*i*][*j*] represents the flow from the *i*th node in the network to the *j*th node. Each number *matrix*[*i*][*j*] must be nonnegative, though it can be zero if there is no flow from node *i* to node *j*. From the [Circos tableviewer example](http://mkweb.bcgsc.ca/circos/guide/tables/):
+
+```js
+const matrix = [
+  [11975,  5871, 8916, 2868],
+  [ 1951, 10048, 2060, 6171],
+  [ 8010, 16145, 8090, 8045],
+  [ 1013,   990,  940, 6907]
+];
+```
+
+The return value of *chord*(*matrix*) is an array of *chords*, where each chord represents the combined bidirectional flow between two nodes *i* and *j* (where *i* may be equal to *j*) and is an object with the following properties:
+
+* `source` - the source subgroup
+* `target` - the target subgroup
+
+Each source and target subgroup is also an object with the following properties:
+
+* `startAngle` - the start angle in radians
+* `endAngle` - the end angle in radians
+* `value` - the flow value *matrix*[*i*][*j*]
+* `index` - the node index *i*
+
+The chords are typically passed to [d3.ribbon](#ribbon) to display the network relationships. The returned array includes only chord objects for which the value *matrix*[*i*][*j*] or *matrix*[*j*][*i*] is non-zero. Furthermore, the returned array only contains unique chords: a given chord *ij* represents the bidirectional flow from *i* to *j* *and* from *j* to *i*, and does not contain a duplicate chord *ji*; *i* and *j* are chosen such that the chord’s source always represents the larger of *matrix*[*i*][*j*] and *matrix*[*j*][*i*].
+
+The *chords* array also defines a secondary array of length *n*, *chords*.groups, where each group represents the combined outflow for node *i*, corresponding to the elements *matrix*[*i*][0 … *n* - 1], and is an object with the following properties:
+
+* `startAngle` - the start angle in radians
+* `endAngle` - the end angle in radians
+* `value` - the total outgoing flow value for node *i*
+* `index` - the node index *i*
+
+The groups are typically passed to [d3.arc](https://github.com/d3/d3-shape#arc) to produce a donut chart around the circumference of the chord layout.

+
+Generates a ribbon for the given *arguments*. The *arguments* are arbitrary; they are simply propagated to the ribbon generator’s accessor functions along with the `this` object. For example, with the default settings, a [chord object](#_chord) expected:
+
+```js
+const ribbon = d3.ribbon();
+
+ribbon({
+  source: {startAngle: 0.7524114, endAngle: 1.1212972, radius: 240},
+  target: {startAngle: 1.8617078, endAngle: 1.9842927, radius: 240}
+}); // "M164.0162810494058,-175.21032946354026A240,240,0,0,1,216.1595644740915,-104.28347273835429Q0,0,229.9158815306728,68.8381247563705A240,240,0,0,1,219.77316791012538,96.43523560788266Q0,0,164.0162810494058,-175.21032946354026Z"
+```
+
+Or equivalently if the radius is instead defined as a constant:
+
+```js
+const ribbon = d3.ribbon()
+    .radius(240);
+
+ribbon({
+  source: {startAngle: 0.7524114, endAngle: 1.1212972},
+  target: {startAngle: 1.8617078, endAngle: 1.9842927}
+}); // "M164.0162810494058,-175.21032946354026A240,240,0,0,1,216.1595644740915,-104.28347273835429Q0,0,229.9158815306728,68.8381247563705A240,240,0,0,1,219.77316791012538,96.43523560788266Q0,0,164.0162810494058,-175.21032946354026Z"
+```
+
+If the ribbon generator has a context, then the ribbon is rendered to this context as a sequence of path method calls and this function returns void. Otherwise, a path data string is returned.
