  Our presentation is aimed at data centers providing access to complex
observational and theoretical data and to the users of these resources. We show
how to visualize complex datasets stored in the VO enabled data archives using
existing VO client software and PLASTIC, a prototype of an application
messaging protocol, for interaction between archive query results and tools. We
demonstrate how to display and explore observable IFU datasets, provided within
the ASPID-SR archive, using CDS Aladin, ESA VOSpec, and VO-Paris Euro3D Client.
In the second part of the paper we show how to use TOPCAT for displaying
results of N-body simulations of galaxy mergers available in the HORIZON GalMer
database.
