Abstract We present a set of interactive techniques for the visual analysis of multi‐dimensional categorical data. Our approach is based on multiple correspondence analysis (MCA), which allows one to analyse relationships, patterns, trends and outliers among dependent categorical variables. We use MCA as a dimensionality reduction technique to project both observations and their attributes in the same 2D space. We use a treeview to show attributes and their domains, a histogram of their representativity in the data set and as a compact overview of attribute‐related facts. A second view shows both attributes and observations. We use a Voronoi diagram whose cells can be interactively merged to discover salient attributes, cluster values and bin categories. Bar chart legends help assigning meaning to the 2D view axes and 2D point clusters. We illustrate our techniques with real‐world application data.

We present a visual analytics solution designed to address prevalent issues in the area of Operational Decision Management (ODM). In ODM, which has its roots in Artificial Intelligence (Expert Systems) and Management Science, it is increasingly important to align business decisions with business goals. In our work, we consider decision models (executable models of the business domain) as ontologies that describe the business domain, and production rules that describe the business logic of decisions to be made over this ontology. Executing a decision model produces an accumulation of decisions made over time for individual cases. We are interested, first, to get insight in the decision logic and the accumulated facts by themselves. Secondly and more importantly, we want to see how the accumulated facts reveal potential divergences between the reality as captured by the decision model, and the reality as captured by the executed decisions. We illustrate the motivation, added value for visual analytics, and our proposed solution and tooling through a business case from the car insurance industry.

We characterize the design space of the algorithms that sequentially tile a rectangular area with smaller, fixed-surface, rectangles. This space consist of five independent dimensions: Order, Size, Score, Recurse and Phrase. Each of these dimensions describe a particular aspect of such layout tasks. This class of layouts is interesting, because, beyond encompassing simple grids, tables and trees, it also includes all kinds of treemaps involving the placement of rectangles. For instance, Slice and dice, Squarified, Strip and Pivot layouts are various points in this five dimensional space. Many classic statistics visualizations, such as 100% stacked bar charts, mosaic plots and dimensional stacking, are also instances of this class. A few new and potentially interesting points in this space are introduced, such as spiral treemaps and variations on the strip layout. The core algorithm is implemented as a JavaScript prototype that can be used as a layout component in a variety of InfoViz toolkits.

Today's generic data management applications such as accounting, CRM or logging and tracking software, rely on form and menu based interfaces. These applications take only marginal advantage of current graphical user interfaces. This is because the data they handle does not have intrinsic visual representations upon which direct manipulation principles can be used. This article presents how we have extended an Information Visualization framework with generic data manipulation functions. These new data editing capabilities are tuned to take advantage of the characteristics of each view. They enable us to generalize the direct manipulation mechanisms to address many abstract data manipulation needs. In this article we present five uses of the features we have implemented and deduce a general workflow applicable to a variety of contexts. The workflow comprises three steps and five editing actions. The steps are: adjust view, select, and edit. The editing actions are: edit a value or group of values, clone objects, remove objects, add attributes, and remove attributes. The workflow provides complete editing access to table and hierarchical data structures using particularly terse interaction methods. It defines a general data editing model that enables powerful data manipulation tasks without requiring end-user programming or scripting.

The proliferation of multiple toolbars and UI widgets around the perimeter of application windows is an indication that the traditional GUI design of a single menubar is not sufficient to support large scale applications with numerous functions. In this paper we describe a new widget which is an enhancement of the traditional menubar which dramatically increases menu-item capacity. This widget, called the Hotbox combines several GUI techniques which are generally used independently: accelerator keys, modal dialogs, pop-up/pull down menus, radial menus, marking menus and menubars. These techniques are fitted together to create a single, easy to learn yet fast to operate GUI widget which can handle significantly more menu-items than the traditional GUI menubar. We describe the design rationale of the Hotbox and its effectiveness in a large scale commercial application. While the Hotbox was developed for a particular application domain, the widget itself and the design rationale are potentially useful in other domains.

An experimental GUI paradigm is presented which is based on the design goals of maximizing the amount of screen used for application data, reducing the amount that the UI diverts visual attentions from the application data, and increasing the quality of input. In pursuit of these goals, we integrated the non-standard UI technologies of multi-sensor tablets, toolglass, transparent UI components, and marking menus. We describe a working prototype of our new para-digm, the rationale behind it and our experiences introduc-ing it into an existing application. Finally, we presents some ot the lessons learned: prototypes are useful to break the barriers imposed by conventional GUI design and some of their ideas can still be retrofitted seamlessly into products. Furthermore, the added functionality is not measured only in terms of user performance, but also by the quality of interaction, which allows artists to create new graphic vocabularies and graphic styles.

We propose an interaction technique for editing splines that is aimed at professional graphic designers. These users do not take full advantage of existing spline editing software because their mental representations of drawings do not match the underlying conceptual model of the software. Although editing splines by specifying control points and tangents may be appropriate for engineers, graphic designers think more in terms of strokes, shapes, and gestures appropriate for editing drawings. Our interaction technique matches the latter model: curves can be edited by means of marks, similar to the way strokes are naturally overloaded when drawing on paper. We describe this interaction technique and the algorithms used for its implementation.
