It is used as a third phase of the Sugiyama algorithm. The algorithm runs in three phases: \begin{enumerate} \item Alignment (4x) \item Horizontal Compactation (4x) \item Balancing \end{enumerate} The alignment and horizontal compactification phases are calculated downward, upward, left-to-right and right-to-left. The four resulting layouts are combined in a balancing step. Warning: The implementation is known to not always produce a correct layout. Therefore this Algorithm is for testing purpose only. The implementation is based on: \begin{itemize} \item Ulrik Brandes, Boris Köpf: Fast and Simple Horizontal Coordinate Assignment. \emph{LNCS} 2002, Volume 2265/2002, pp. 33--36 \end{itemize} ]] example [[ \tikz \graph [SugiyamaLayout, FastSimpleHierarchyLayout] { a -- {b,c,d} -- e -- a; }; ]] -------------------------------------------------------------------- -------------------------------------------------------------------- key "FastSimpleHierarchyLayout.layerDistance" summary "Distance between the cetners of nodes of two consecutive layers." documentation [[ Sets the (minimum?) distance between nodes on two consecutive layers.
