								<h2>Hierarchical layout difference</h2>
							 | 
						|
								<div style="width:700px; font-size:14px; text-align: justify;">
							 | 
						|
								  This example shows a the effect of the different hierarchical layout methods. Hubsize is based on the amount of edges connected to a node.
							 | 
						|
								  The node with the most connections (the largest hub) is drawn at the top of the tree. The direction method is based on the direction of the edges.
							 | 
						|
								  Try switching between the methods with the dropdown box below.
							 | 
						|
								</div>
							 | 
						|
								Layout method:
							 | 
						|
								<select id="layout">
							 | 
						|
								  <option value="hubsize">hubsize</option>
							 | 
						|
								  <option value="directed">directed</option>
