/**
|
|
* This is a basic example on how to instantiate sigma. A random graph is
|
|
* generated and stored in the "graph" variable, and then sigma is instantiated
|
|
* directly with the graph.
|
|
*
|
|
* The simple instance of sigma is enough to make it render the graph on the on
|
|
* the screen, since the graph is given directly to the constructor.
