<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="../samples/Fishbone.html">fishbone layout</a>
extension page for a diagram format typically used in root cause analysis.

<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>.

<hr>
<!-- blacklist tags that do not correspond to a specific GoJS feature -->
<h4>Buttons</h4>
<p>
GoJS defines several <a href="../api/symbols/Panel.html" target="api">Panel</a>s for common uses.
These include "Button", "TreeExpanderButton", "SubGraphExpanderButton", "PanelExpanderButton", "ContextMenuButton", and "CheckBoxButton".
"ContextMenuButton"s are typically used inside of "ContextMenu" Panels;
"CheckBoxButton"s are used in the implementation of "CheckBox" Panels.
</p>
<p>
These predefined panels can be used as if they were <a href="../api/symbols/Panel.html" target="api">Panel</a>-derived classes in calls to <a href="../api/symbols/GraphObject.html#build" target="api">GraphObject.build</a>.
They are implemented as simple visual trees of <a href="../api/symbols/GraphObject.html" target="api">GraphObject</a>s in <a href="../api/symbols/Panel.html" target="api">Panel</a>s,
with pre-set properties and event handlers.
