Hi, everyone!
I have ask the same question on stack overflow
<http://stackoverflow.com/questions/23929074/how-can-i-align-nodes-horizontally-when-rankdir-lr-in-graphviz>.
But I have not get any answer there. Maybe I ask in the wrong place. I
decide to try again here.
I am struggling with a graph, hoping to align nodes, but this seems to be
difficult. My current code (attach at the last) generate the follow graph
or see this link <http://ge.tt/3LlXw8i1/v/0?c?c>.

First, I want the I0, I1, I8, I12 to align horizontally. Does it have to
use subgraph to wrap up some nodes? If it does, how? I have tried wrap I0,
I1 nodes and the edge from I0 to I1 with a subgraph for a test. But that
didn’t make much change.
Secondly, can the self-loop in I5 look more elegant like the self-loop in
I4 but not at the top of the node. I only find portpos option. If the node
is a circle, the portpos option is enough. But it looks strange with
rectangle.
Thanks!
