The equilibrium placement naturally embeds the graph in a Euclidean space, namely 3 . The first vertex of the graph is placed in position (0, 0, 0) = 0 3 , which is allowed because any translation of the equilibrium placement still results in an equilibrium placement. Moreover, because of Equation , for any vertex identifier u ∈ V there is an offset o such that p(u, o) ∈ [0, 1 [ 3 , where [a, b [ designates the set of reals between a (included) and b (excluded). In order to simplify the representation, this offset is set to 0 3 by adjusting the offsets of the edges of the graph accordingly. In this new representation, equations 1 and 2 still hold, as well as the new property:
