layout a <a class="el" href="a01741.html" title="A rooted tree data structure.">vtkTree</a> into a tree map
<p>
<a class="el" href="a00121.html" title="layout a vtkTree into a tree map">vtkAreaLayout</a> assigns sector regions to each vertex in the tree, creating a tree ring. The data is added as a data array with four components per tuple representing the location and size of the sector using the format (StartAngle, EndAngle, innerRadius, outerRadius).<p>
This algorithm relies on a helper class to perform the actual layout. This helper class is a subclass of <a class="el" href="a00122.html" title="abstract superclass for all area layout strategies">vtkAreaLayoutStrategy</a>.<p>
