 n systems allow for synthesizing customized visualizations by analyzing da
 ta and suggesting how to encode each variable of the data. Although a few 
 powerful systems have been developed\, these can only handle tabular data 
 which often comes from statistics. None of these tools is aware of RDFS an
 d OWL and thus\, at most\, the RDF graph's structure can be visualized as 
 a node-link diagram.    The visualization design system we propose\, close
 s this gap and allows to refer directly to RDFS and OWL terms in the visua
 l mappings. Characteristics of properties such as transitivity or symmetry
  and inverse relations are exploited for visualizing. Thereby\, the system
  supports the inhomogeneous character of RDFS data having many different t
 ypes of relations. In RDF\, entities are often not only described using si
 mple data types\, but by their relations to other complex objects. We focu
 s on visual means\, which are suitable for representing exactly these rela
 tionships.     The visual design system is approached in three steps: Firs
 t\, we formalize knowledge from the field of visualization and graphics as
  the Visualization Ontology (VISO). Second\, based on this\, we develop a 
 declarative RDF Visualization Language (RVL) that allows for describing un
 iversally identifiable and composable mappings. This language is described
  by a schema that syntactically and semantically constraints the allowed m
 appings from RDFS properties\, classes and individuals to the visual means
  defined in the VISO. Third\, we use the schema of the language in order t
 o build a prototypical RVL editor.     Betreuer: Prof. Dr. Uwe Aßmann  Fa
