This article presents a modification of Kamada-Kawai method (KK) which was designed to produce layouts of simple undirected graphs. Graphs drawn by Kamada-Kawai algorithm exhibit symmetries, tend to ...

We present an extremely fast graph drawing algorithm for very large graphs, which we term ACE (for Algebraic multigrid Computation of Eigenvectors). ACE exhibits an improvement of something like two ...
