Automatic drawing of compound digraphs for a real-time power system simulator

Two implemented versions of a compound digraph algorithm using an object-oriented approach are shown for use in the field of automatic drawing of electrical circuit diagrams. One is a test version with minimal user interface, the other a full-fledged editor part of a graphical user interface project currently under development. Orthogonal drawing of edges and interactive implosion and explosion of compound vertices are key features of the application.
