OO is not just a bunch of nodes with pointers. You can do that in raw C without OO. OO *adds* dynamic polymorhism to the mix, which means that the runtime graph, can be very different from the source code graph. OO allows dependencies within the graph to be inverted from the source code viewpoint. This means that from the source code view you don't have a graph at all; rather you have a suite of many tiny graphlets all seemingly independent of each other.
