- "As mentioned in Tutorial 1, contact layers are the graph connecting the people in the simulation. Each person is a node, and each contact is an edge. While enormous complexity can be used to define realistic contact networks, a reasonable approximation in many cases is random connectivity, often with some age assortativity. Here is an example for generating a new contact layer, nominally representing public transportation, and adding it to a simulation:"
