Arguably a graph layout is performed by a kind of "training" in the sense that it takes many iterations for the parameters (and possibly physical distancing forces) to be evaluated for every node against all of the others. This is a solver, and not entirely unlike something like gradient descent. This is painting a rather broad brush with these terms, however.
