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="FishboneLayout.js" target="_blank">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.
