Abstract
The difficulty to build interactive visualizations that allow complex data explorations is a well-known fact. Some reasons for this difficulty are the dynamic nature of data exploration process and the diversity of goals and requirements in visualization applications, among others. The usage of design models for implementing information visualization systems (IVS) appears as a convenient approach to reduce this complexity. However, current HCI design models are insufficient from the point of view of the needs of IVSs. In a similar way, tools or environments specially developed to build IVSs have limitations for the implementation of highly dynamic exploration process. In this work, MAMP, a design model for the construction of object oriented visualization applications is presented. This model combines the advantages of current HCI design models (in particular, MVC) with the requirements of data visualization process. A software architecture and an object-oriented application framework, Telescope, based on MAMP are also described, along with several ways for implementing the characteristic features of any visualization, using these tools. Finally, two visualization applications developed according to the MAMP design model are briefly described: CityVis,a system for visualizing city data, and WarVis, a system for visualizing information about military conflicts.
