Hello Sean!

Thank you for your feedback.

> The only technical concern I immediately see is that there's an implicit risk assumed.  Namely the use of the GOBLIN library is an unknown quantity since we've not worked with it before.  There should be some evaluation time allocated and a contingency plan in place should it not work out for whatever reason.

Just to make sure, the purpose of one of this graph libraries is to
help me in applying graph algorithms for the interactive part of the
application.

GOBLIN got my attention because it was mentioned in the description of
the project and after a bit of a discussion with Cliff Yapp it seemed
to me that it would be useful. You are right, I should allocate some
research time to dig deeper and see if it's a doable plan.

As alternatives, I've also considered working with the Adaptagrams
library, http://adaptagrams.sourceforge.net/ or with the Open Graph
Drawing Framework library, http://www.ogdf.net/doku.php, but these
would also imply the same steps as the ones mentioned in the GOBLIN
case.

A contingency plan that I'd take into account would be to use the
Boost Graph Library (BGL),
http://www.boost.org/doc/libs/1_49_0/libs/graph/doc/index.html, for
the usage of graph algorithms in the interactively display scenario.

Do correct me if I'm wrong in any of these affirmations.


Best regards,
