The following bug exists also as sourceforge bug request:
[ 778394 ] GraphViz Interface
boost version is 1.30.0
Because Jeremy seems to be reactivated and the sourceforge tracker status is still 'open'
a small reminder:
For an adjacency list of the following form
adjacency_list
write_graphviz produces the following graph structure
--- output begin ---
graph G {
graph [splines=false bgcolor=lightgrey]
node [shape=circle color=red]
edge [style=solid]
002F48A0[label ="", height="0.1", pos="540,250"];
002F4978[label ="", height="0.1", pos="278,321"];
002F4A50[label ="", height="0.1", pos="198,67"];
002F4B28[label ="", height="0.1", pos="163,27"];
002F4C00[label ="", height="0.1", pos="442,487"];
002F4B28--002F4A50 ;
002F4A50--002F4978 ;
002F4978--002F4B28 ;

002F48A0--002F4A50 ;
002F4978--002F48A0 ;
002F48A0--002F4C00 ;
002F4C00--002F4978 ;
}
--- output end ---
This causes error messages from neato (GraphViz tool):

Error: node 002 in graph G has no position
as required by the -n flag

The reason can be found at:
http://www.research.att.com/~erg/graphviz/info/lang.html
"An ID is any string of alphabetic characters, underscores or digits, but not beginning
with a digit; or a number; or any quoted string possibly containing escaped quotes."
So, the hexadecimal number (mix of digits and characters) of the transfered pointer (list
item) is the problem.I would suggest write_graph_viz quotes the node name or prefixes with
a character or uses a decimal representation.
