Abstract in different language:	Our work is focused on assisting users in exploration of spatially referenced data, i.e., economical, demographic, ecological, etc. data referring to geographical objects or locations. Analysis of such data is impossible without representing them on maps. The main weakness of Geographic Information Systems (GISes) in support of data mapping is that the user is not given any guidance in designing presentations whereas improper selection of visualization methods can impede subsequent analysis or even result in wrong conclusions. Correct map design requires special knowledge from the field of thematic cartography. One cannot presume that any GIS user has this knowledge. We introduce the software system IRIS that incorporates the knowledge on map design in the form of generic, domain-independent rules. On this basis it automatically generates thematic maps properly presenting user’s data. Another distinctive feature of IRIS is that it supports subsequent data analysis with the use of generated maps. The user can interactively manipulate the presentations, and in response they dynamically change making more salient various features of the data under analysis.
