Four metrics were measured over pan-genome graphs created with five construction tools on the 50 SARS-CoV-2 genome instance. We report a the number of vertices of each graph, b the total length of the graph, c the number of potential seeds (k-mers) of length 20, and d the number of vertices used by at least the \(11\%\) of the input sequences. For pangeblocks we report the results of three objective functions: blocks, depth, and weighted (horizontal axis) The metrics for other tools are shown by horizontal lines. The black dotted line corresponds to pggb, the red dashed line corresponds to vg, the orange dash-dot line corresponds to make_prg, and the green dash-dot line corresponds to founderblockgraph. Since make_prg creates a sequence graph, node depth cannot be computed for it
