vertex-cardinality).

> The PageRankBenchmark class, to be a proper benchmark, should run over graphs which look more like data seen in the wild, and web link graphs, social network graphs, and text corpora (represented as a bipartite graph) all have power-law distributions, so benchmarking a synthetic graph which looks more like this would be a nice test which would stress cases of uneven split-distribution and bottlenecks of subclusters of the graph of heavily connected vertices.
