July 4 This paper reviews and illust,rates a direct manipula tion approach to visualization of complex objects called paiidiilg mulliple views. We describe a progra.mming model for direct manipulation in general alld for pa.inting in particular, based on simple constra.ints between entities in an the underlying scientific database a.nd the components of displays used to examine the data. With this model, the original notion of "brushing sca.tterplots" is easily extended.
