Some graph visualizations may turn into "hairball" ( in Turkish: Saç yumağı) when the corresponding graph is too dense. The graph at the side is human protein-protein interactions graphs. Over 25000 genes and its corresponding product protein exist in Human. Its interactions which corresponds to edges are even more than 100000 depending on the interaction types. BIOGRID is one the database that I knew for the PPI networks. Finally, the aim of the visualization system should be rescuing from this hairball results.
