The range of issues considered in graph drawing includes algorithms, graph theory, geometry, topology, order theory, graphic languages, perception, app- cations, and practical systems. Much research is motivated by applications to systems for viewing and interacting with graphs. The interaction between th- retical advances and implemented solutions is an important part of the graph drawing eld. The annually organized graph drawing symposium is a forum for researchers, practitioners, developers, and users working on all aspects of graph visualization and representations. The preceding symposia were held in M- treal (GD'98), Rome (GD'97), Berkeley (GD'96), Passau (GD'95), Princeton (GD'94), and Paris (GD'93). The Seventh International Symposium on Graph Drawing GD'99 was or- nized at Sti r n Castle, in the vicinity of Prague, Czech Republic. This baroque castle recently restored as a hotel and conference center provided a secluded place for the participants, who made good use of the working atmosphere of the conference. In total the symposium had 83 registered participants from 16 countries.
