WebGiven a (0,1 }-matrix M, the graph-realization problem is to determine a connected graph G, if one exists, such that M is a fundamental matrix for G. M is then said to be graphic and G is a realization of M. This definition is equivalent to the one in the Introduction. For any {0, }-matrix M, graphic or not, the set of row indices WebIt turns out that any graph at all can be realized in 3-space because there is enough "room" so that the edges can be chosen in a way so they meet only at the vertices.
