Question

How can I reduce the top and bottom margins of these Graphviz nodes? I am specifying "0.05, 0.0 as the margins to each node, with fontsize = 8.

Answer 1

digraph { rankdir = LR
    node [shape=box margin=0 width=0 height=0]
    asdf [label="asdf\nasdf"]
    qwer [label="qwerqwer"]
    asdf -> qwer
}
