 A stage of the algorithm, interface \code{AlgorithmStage}, is an interval during which each step of the algorithm is performed in a similar way.
 Each time such a step is performed it returns whether the stage is already finished or a breakpoint has been reached.
 For example, a forward step in the stage of calculating one extremal layout, \code{ExtremalLayoutCalc}, consists of either a step of calculating the blocks, \code{BlockCalc}, or a step of compacting the layout, \code{Compaction}.
-All the stages are displayed in class diagram~\ref{fig:animation_and_bk}.
+All the stages are displayed in class diagram~\ref{fig:bk}.
 
 To be able to undo a step each stage needs to implement methods for both forward and backward steps.
