This function generates plot coordinates for each variable in a graph that does not
have them already. To this end, the well-known “Spring” layout algorithm is
used. Note that this is a stochastic algorithm, so the generated layout will be
different every time (which also means that you can try several times until you find
a decent layout).
Usage
graphLayout(x, method = "spring")
Arguments
x
the input graph, of any type.
method
the layout method; currently, only "spring" is supported.
Value
the same graph as x but with layout coordinates added.
