Thanks for the answer.
I see your point, that Ubigraph does some magic* to place vertices and
edges.
This makes me wonder, how they generate the binary tree demo:
http://ubietylab.net/ubigraph/content/Demos/random_binary_tree.html
Is there a way to disable this optimal graph layout determination process?

Ozgur,
I've just compared the way vacuum-ubigraph visualizes binary trees to
the random_binary_tree demo and found that I had missed an important
edge attribute called "oriented", it seems to produce the output you want.
I hope to upload the new package version soon, meanwhile you can do the
following (assuming you use Linux):
cabal unpack vacuum-ubigraph
patch -d vacuum-ubigraph-0.1.0.3/ -p 1 < vacuum-ubigraph-oriented.patch
cd vacuum-ubigraph-0.1.0.3
cabal configure && cabal build && cabal install
diff -rupN vacuum-ubigraph-0.1.0.3/System/Vacuum/Ubigraph.hs vacuum-ubigraph-0.1.0.4/System/Vacuum/Ubigraph.hs
