Well, ah I presume that you at least get the page that says you
must set your name and email address in preferences before you
are allowed access to the edit page, right? Just do that and try
again. It should work.

Great. Let me know what you find. So far the most relevant info
I have found is here:
http://www.graphviz.org/doc/info/output.html
Output Formats
ps2
Produces PostScript output with PDF notations. It is assumed the
output will be directly converted into PDF format. The notations
include PDF bounding box information, so that the resulting PDF file
can be correctly used with pdf tools, such as pdflatex. In addition,
if a node has a URL attribute, this gets translated into PDF code
such that the node, when viewed in a PDF-viewer, e.g., acroread, is
a link to the given URL. If a URL is attached to the graph, this
serves as a base, such that relative URLs on nodes are derived from
it.

I haven't done the hyperlinking yet, but you can see what a
pamphlet file that contains GraphViz commands looks like at:
http://wiki.axiom-developer.org/book--main--1/Endpaper3
This contains both the Algebra and Data Structure diagrams (two
versions, one using abbreviations and one using the full category
names).
Right now I am looking into the problem of writing multi-line
labels that would allow me to write for example:
Homogeneous
Aggregate
instead of
HomogeneousAggregate
This would allow the diagram to be narrower and with a larger
font size. The way this is supposed to be written in GraphViz
"dot" language is:
HomogeneousAggregate [label="Homogeneous\nAggregate"];
but when I write the \n inside the LaTeX file, LaTeX insists
on interpreting this as an undefined command \nAggregate and
gives a LaTeX error instead of just writing it to the '*.dot'
file the way the GraphViz macro says it should. If anyone
know how to get LaTeX to write a string containing \n to a
file, please let me know. Right now I am stuck.
