What is an Object Graph?

When I hear the word “graph,” I always think of graphs on a cartesian coordinate system. That’s not what we’re talking about here. Perhaps the easiest way of introducing graphs is to look at a visual representation of one: What are we looking at here? We see a set of objects represented by circles. The set is [6, 4, 5, 1, 3, 2]. We also see that a subset of those objects have some relationship to one another, which is represented by the lines. »
