     Graphviz (<URL: http://www.graphviz.org>) is open source graph
     visualization software providing several main graph layout
     programs, of which 'dot' makes hierarchical or layered drawings
     of directed graphs, and hence is typically most suitable for
     visualizing classification trees.

     Using 'dot', the representation in file 'foo.dot' can be
     transformed to PostScript or other displayable graphical formats
     using (a variant of) 'dot -Tps foo.dot >foo.ps'.

     Some Weka classifiers (e.g., tree learners such as J48 and M5P)
     implement a Drawable interface providing DOT representations of
     the fitted models.  For such classifiers, the 'write_to_dot'
     method writes the representation to the specified connection.
