d2 generates asymmetric figure

[ningcng]

A -> B
A -> C
C -> B
B -> C
B -> D
C -> E

B and C, D and E should be symmetric but the generated figured is not.

To clarify, I think the desired layout is to have B and C on the same level, and then D and E on the same level below, with horizontal edges between B and C (on the same level).

Like this but with the horizontal edges between B and C.

That being said I don't know if dagre really supports edges between nodes on the same level since it interprets an edge between them to mean they should be on different levels.
