This is what a simple Canvas sub-scenegraph may look like: | |||
<syntaxhighlight lang="text">MatrixTransform { | |||

To dump the scene graph of the whole Canvas, just invoke the <code>dumpSceneGraph()</code> method on the top-level root node like this: | |||
<syntaxhighlight lang="nasal"> | |||
root.dumpSceneGraph('my-canvas-scenegraph.osg'); | |||
</syntaxhighlight> | |||
