This test suite is proposed for the comparison of three-dimensional orthogonal graph drawing algorithms. It is composed by 1900 randomly generated graphs having from 5 to 100 vertices, 20 graphs for each value of vertex cardinality. All the graphs are connected, with maximum vertex degree six, without multiple edges and self-loops. The number of edges is twice the number of vertices.
We split the test suite in two files to ease the download operations.
