force-directed
+graph layout algorithm.  It applies repulsion between all vertex pairs (to 
avoid overlap)
+and attraction between connected vertices (to pull them together).  Forces 
decay with
+distance, and a global temperature limits maximum displacement per iteration, 
causing the
+layout to sta0bilize gradually.")
