Bipartite incidence pattern for Enron Email

Graph Summary

Two-way graph uses anonymized sender and receiver identifiers.

The primary benchmark graph is built from unique (id1, id2) pairs. The figure shows a binned sparsity pattern of the bipartite incidence block, with both partitions relabeled to contiguous integer identifiers. This block is the off-diagonal part of the corresponding graph Laplacian.
