Re: [eclipse-users] Help with displaying a binary tree with graphviz

Hi,

In your first graph, there are only one edge from each node, so I am not 
sure if it is possible to display each node to the side in the way you 
want using graphviz, which will have no knowledge that each of your node 
is `missing' the other edge. For debugging purposes, if you display the 
edges as well as the nodes, then it seems to me there will be no 
confusion, as you can clearly see that there is one edge coming out of 
the node in such cases.

Cheers,

Kish
