<p>
<em>Fault trees</em> are used to conduct deductive failure analysis in which an undesired state of a
system is analyzed using Boolean logic to combine a series of lower-level events.
</p>
<p>
This diagram uses a basic <a>TreeModel</a> and <a>TreeLayout</a> to layout nodes in a tree structure.
The <a>Diagram.nodeTemplate</a> definition allows for text describing the undesirable states and,
when necessary, a figure indicating an event/gate.
</p>
<p>
The <b>visible</b> property on some of the node template's <a>Shape</a>s is set based on
whether a figure is chosen for the node in the <a>Model.nodeDataArray</a>. The nodes also
display a <b>TreeExpanderButton</b> allowing for expanding/collapsing of subtrees.
See the <a href="../intro/buttons.html">Intro page on Buttons</a> for more GoJS button information.
</p>
<p>
Related to deductive failure analysis is root cause analysis, or RCA. See the <a href="../extensions/Fishbone.html">fishbone layout</a>
extension page for a diagram format typically used in root cause analysis.
