| <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. | |
