							|  | <h2>Static smooth curves</h2> | 
						
						
							|  | <div style="width:700px; font-size:14px; text-align: justify;"> | 
						
						
							|  |     All the smooth curves in the examples so far have been using dynamic smooth curves. This means that each curve has a | 
						
						
							|  |     support node which takes part in the physics simulation. For large networks or dense clusters, this may not be the ideal | 
						
						
							|  |     solution. To solve this, static smooth curves have been added. The static smooth curves are based only on the positions of the connected | 
						
						
							|  |     nodes. There are multiple ways to determine the way this curve is drawn. This example shows the effect of the different | 
						
						
							|  |     types. <br /> <br /> | 
						
						
							|  |     Drag the nodes around each other to see how the smooth curves are drawn for each setting. For animated system, we | 
						
						
							|  |     recommend only the continuous mode. In the next example you can see the effect of these methods on a large network. Keep in mind | 
						
						
							|  |     that the direction (the from and to) of the curve matters. | 
						
						
							|  |     <br /> <br /> |
