dot notation for horizontal flow

Question

I have a graph which is shallow than deep. I wanted it to flow horizontally instead of vertically as is the default.

E.g. instead of

    a 
  /   \
b       c

I want

    b
  /
a
  \
    c

Can we do this in DOT notation?

Answer 1

Yes. At the top of your graph add:

digraph example {
  rankdir=LR;
  a -> b
  a -> c
}

This will orient the graph from left to right.
