Classification: UNCLASSIFIED Caveats: NONE Not a boost programming question exactly. I am mostly a visual analytics (VA) programmer using X3D to interact/navigate w/i a visualization. And for most of the past year learning/using BGL to build and traverse small graphs represention, e.g. terrorist networks, for information discovery. Is there just 1 existing parser (AT&T Graphviz DOT) for r/w from a text file? This format is quite good for examining graphs; and maybe it can do 3D position vectors. But just wondering if I should consider others for 3D display of networks, and for a visual analytics technology. Hope this q is appropriate, or maybe I should become more familiar with BGL first.
