Also this paper might be interesting as well. It concludes and categories graph layouts algorithms. Depending what information you want to visualize and what the data looks like, you can pick up different algorithms. http://profs.etsmtl.ca/mmcguffin/research/2012-mcguffin-simp...
Try to read this paper. They mentioned several graph layout algorithms.I think you can also try to ask them the source code. http://www.cs.ubc.ca/labs/imager/tr/2006/Archambault_TopoLay...
