<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.
