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
