<h2>Hierarchical Layout - Scale-Free-Network</h2>
|

<div style="width:700px; font-size:14px; text-align: justify;">
|

This example shows the randomly generated <b>scale-free-network</b> set of nodes and connected edges from example 2.

In this example, hierarchical layout has been enabled and the vertical levels are determined automatically.
