uses the squarify tree map layout algorithm
<p>
<a class="el" href="a01601.html" title="uses the squarify tree map layout algorithm">vtkSquarifyLayoutStrategy</a> partitions the space for child vertices into regions that use all avaliable space and are as close to squares as possible. The algorithm also takes into account the relative vertex size.<p>
