In the visualization process of biochemical networks it
often happens that two or more graphs are dealt with at the same
time. Then the user has to recognize equal substructures in
different graphs which may be drawn in a totally different way. This project deals with the task to draw equal
substructures in different graphs in the same way. Then the rest of the
graphs can be drawn by different aesthetic criteria. The project
covers both theoretical and practical aspects of the problem.
