I have a trouble assigning the same rank to record nodes. Without node [shape=record] the graph works. Uncommenting that line and there's lost B C edge error.
graph {
rankdir=LR
// uncommenting the following line gives "lost B C edge" error
// node [shape=record]
A--B
A--C
B--C
{
rank=same
B
C
}
}
I do need record shape in my actual graph. I'm not just using it to get rectangular shape for nodes.
