In no way, unless you expect conscious behavior of carbon atoms :)
I would look on the problem from the other side: C atoms can have 2 (linear), 3 (flat with 120 deg between bonds) or 4 (tetrahedra) fold coordination and thus can sit in the line, in the flat or in the volume. When 3-fold coordinated atoms occasionally happen to be in a large quantity we call it graphene.
People have invented a number of methods to increase the probability of this process, CVD on Cu for example.

this because of sp2 hybridization of carbon atoms.
read basics about this you can get a clear idea.
