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 on a large network.
Also shown in this example is the inheritColor option of the edges as well as
the roundness factor.
To improve performance, the physics have been disabled with:
{barnesHut: {gravitationalConstant: 0, centralGravity: 0,
springConstant: 0}} and we have enabled
the toggle hideEdgesOnDrag.

inheritColor option:
Roundness (0..1): (0.5 is max roundness for continuous, 1.0
for the others)
