This sample shows a "fishbone" layout of a tree model of cause-and-effect relationships. This type of layout is often seen in root cause analysis, or RCA.
The layout is defined in its own file, as <a href="../extensions/FishboneLayout.js">FishboneLayout.js</a>. When using FishboneLayout the diagram uses FishboneLink in
order to get custom routing for the links.
</p>
<p>The buttons each set the <a>Diagram.layout</a> within a transaction.</p>

<h3 class="text-xl">GoJS Features in this sample</h3>
<!-- blacklist tags that do not correspond to a specific GoJS feature -->
<h4>Collections</h4>
<p>
<b>GoJS</b> provides its own collection classes: <a href="../api/symbols/List.html" target="api">List</a>, <a href="../api/symbols/Set.html" target="api">Set</a>, and <a href="../api/symbols/Map.html" target="api">Map</a>.
You can iterate over a collection by using an <a href="../api/symbols/Iterator.html" target="api">Iterator</a>.
More information can be found in the <a href="../intro/collections.html">GoJS Intro</a>.
</p>
<p>
<a href="../samples/index.html#collections">Related samples</a>
</p>
<hr>
<!-- blacklist tags that do not correspond to a specific GoJS feature -->
<h4>Links</h4>
<p>
The <a href="../api/symbols/Link.html" target="api">Link</a> class is used to implement a visual relationship between nodes.
Links are normally created by the presence of link data objects in the <a href="../api/symbols/GraphLinksModel.html#linkDataArray" target="api">GraphLinksModel.linkDataArray</a>
or by a parent key reference as the value of the <a href="../api/symbols/TreeModel.html#nodeParentKeyProperty" target="api">TreeModel.nodeParentKeyProperty</a> of a node data object
in a <a href="../api/symbols/TreeModel.html" target="api">TreeModel</a>.
More information can be found in the <a href="../intro/links.html">GoJS Intro</a>.
</p>
<p>
<a href="../samples/index.html#links">Related samples</a>
</p>
<hr>
<!-- blacklist tags that do not correspond to a specific GoJS feature -->
<h4>Tree Layout</h4>
<p>
This predefined layout is used for placing Nodes of a tree-structured graph in layers (rows or columns).
For discussion and examples of the most commonly used properties of the <a href="../api/symbols/TreeLayout.html">TreeLayout</a>,
see the <a href="../intro/trees.html">Trees</a> page in the Introduction.
More information can be found in the <a href="../intro/layouts.html#TreeLayout">GoJS Intro</a>.
</p>
<p>
<a href="../samples/index.html#treelayout">Related samples</a>
</p>
<hr>
<!-- blacklist tags that do not correspond to a specific GoJS feature -->
<h4>Custom Layouts</h4>
<p>
GoJS allows for the creation of custom layouts to meet specific needs.
</p>
<p>
There are also many layouts that are extensions -- not predefined in the <code>go.js</code> or <code>go-debug.js</code> library,
but available as source code in one of the three extension directories, with some documentation and corresponding samples.
More information can be found in the <a href="../intro/layouts.html#CustomLayouts">GoJS Intro</a>.
</p>
<p>
<a href="../samples/index.html#customlayout">Related samples</a>
</p>
<hr>
<!-- blacklist tags that do not correspond to a specific GoJS feature -->
<h4>GoJS Extensions</h4>
<p>
<b>GoJS</b> can be extended in a variety of ways.
The most common way to change the standard behavior is to set properties on the <a href="../api/symbols/GraphObject.html" target="api">GraphObject</a>, <a href="../api/symbols/Diagram.html" target="api">Diagram</a>, <a href="../api/symbols/CommandHandler.html" target="api">CommandHandler</a>, <a href="../api/symbols/Tool.html" target="api">Tool</a>, or <a href="../api/symbols/Layout.html" target="api">Layout</a>.
But when the desired property does not exist, you might need to override methods of CommandHandler, Tool, Layout, Link, or Node.
Methods that you can override are documented in the API reference.
Various features of GoJS can be overriden, either by replacing a method on an instance (a feature of JavaScript) or by defining a subclass.
You should not modify the prototypes of any of the <b>GoJS</b> classes.
</p>
<p>
In addition to our samples, <b>GoJS</b> provides an <strong><a href="../samples/#extensions">extensions gallery</a></strong>,
showcasing the creation of custom tools and layouts.
Those classes and samples are written in TypeScript, available at <code>../extensionsJSM/</code>,
as ECMAScript/JavaScript modules -- these use the <code>../release/go-module.js</code> library.
We recommend that you copy the files that you need into your project, so that you can adjust how they refer to the GoJS library
that you choose and so that you can include them into your own building and packaging procedures.
