“…In this particular chapter, we focus on four models: Snap (North, 2002), presentation graphics (McDonald et al, 1990) and the View Coordination Architecture (Pattison and Phillips, 2001) and a Layered Model for Coordination (Boukhelifa et al, 2003). Andrieko et al (this volume,Chapter 5) provide an in depth discussion of software issues in geovisualization.…”

“…Rather than concentrating on the implementation architecture, our work has focussed on a layered approach that is based on the dataflow model (Roberts, 1999;Boukhelifa et al, 2003) and incorporates more layers than that of Pattison and Phillips (2001). In this approach, the coordination may occur between any parameter at any level of the visualization flow (Figure 8.6).…”

“…Although Pattison and Phillips (2001) disagree by saying that there are additional forms of coordination other than selection and navigation, for example, "coordinating the data in preparation for the visualization such as sorting, averaging or clustering". Likewise, Roberts (1999) believes in a broader use of coordination, exemplified by the layered model (Roberts, 1999;Boukhelifa et al, 2003) where the user may link any aspect of the dataflow and exploration process. 309 310 311 312 313 314 315 316 317 318 319 320 321 322 323 324 325 326 327 328 329 330 331 332 333 334 335 336 337 338 339 340 341 342 343 344 345 346 347 348 349 350 351 352 Selection allows the user to highlight one or many items either as a choice of items for a filtering operation or as an exploration in its own right; this is often done by direct manipulation where the user directly draws or wands the mouse over the visualization itself (Cleveland and McGill, 1988;Ward, 1994).…”

“…Recent research has focussed on providing principles for multiple views (Baldonado et al, 2000) and examining linking methods such as Roberts' taxonomy of coordination (Roberts, 1999;Boukhelifa et al, 2003) and North's Snap-together system (North and Shneiderman, 2000a) that allows unforeseen combinations of coordinated visualizations. This research is opening the way for more expressive investigation environments that support the user in their task rather than distracting the user from their task.…”

Exploratory Visualization with Multiple Linked Views

Exploratory visualization enables the user to test scenarios and investigate possibilities. Through an exploration, the user may change various parameter values of a visualization system that in turn alters the appearance of the visual result. For example, the changes made may update what information is being displayed, the quantity or resolution of the information, the type of the display (say) from scatter plot to line-graph. Furthermore, the user may generate additional windows that contain the visual result of the new parameters so they can compare different ideas side-by-side (these multiple views may persist such that the user can compare previous incarnations). Commonly these windows are linked together to allow further investigation and discovery, such as selection by brushing or combined navigation. There are many challenges, such as linking multiple views with different data, initializing the different views, indicating to the user how the different views are linked. This chapter provides a review of current multiple linked-view tools, methodologies and models, discusses related challenges and ideas, and provides some rudiments for coordination within a geovisualization context. The types and uses of coordination for exploratory visualization are varied and diverse, these ideas are underused in geovisualization and exploratory visualization in general. Thus, further research needs to occur to develop specific geovisualization reference models and extensible systems that incorporate the rich variety of possible coordination exploration ideas. IntroductionThis chapter advocates the use of many lightweight views that are linked together. They are lightweight in that they are: (i) easy to generate by the user, where the user does not spend unnecessary time and effort to explicitly link the new view to existing ones; and (ii) do not take many computer resources (e.g., memory, computation).

“…The work presented in this paper is a substantially updated and revised version of the paper presented at CMV2003, 1 in particular the implementation is entirely new. This paper is divided into the following sections: related work; discussion of the salient features of coordination in exploratory visualization; the new model; discussion about the relationship of the model to current coordinated visualization systems; model implementation; and future work and conclusions.…”

A Model and Software System for Coordinated and Multiple Views in Exploratory Visualization

This paper describes a model for expressing coordination in multiple view visualization systems. We present the model and describe a prototype implementation that illustrates the features of the model. Current visualization systems tend to have an informal and inconsistent approach to coordination. Our model takes a formal approach to describing widely used coordination concepts. The model is based on views sharing abstract objects such as the visualization parameters of the dataflow model. Additionaly, this paper describes how current coordinations in exploratory visualization work and how novel coordinations can be constructed using our model.
