     used.

     graphvizVersion()

_V_a_l_u_e:

     A list with two elements, each of class 'numeric_version'. The
     first element named 'installed_version' represents the version of
     Graphviz that is being used by the package. The second element
     named 'build_version' represents the version of Graphviz that was
     used to build the package. A mismatch between these two versions
     may indicate problems.
