<p>A <em>parse tree</em> is an ordered, rooted tree representing the structure of a sentence, broken down to parts-of-speech.</p>
<p>
This diagram uses a custom <a>TreeLayout</a> called <b>FlatTreeLayout</b> that places all leaf nodes at the same Y position.
It also makes use of a <b>TreeExpanderButton</b> on the node template. See the <a href="../intro/buttons.html">Intro page on Buttons</a> for more GoJS button information.
