Casual Information Visualization: Depictions of Data in Everyday Life
Publication Year: 2007, Page(s):1145 - 1152
Cited by: Papers (89)Information visualization has often focused on providing deep insight for expert user populations and on techniques for amplifying cognition through complicated interactive visual models. This paper proposes a new subdomain for infovis research that complements the focus on analytic tasks and expert use. Instead of work-related and analytically driven infovis, we propose casual information visuali... View full abstract»

Geographically Weighted Visualization: Interactive Graphics for Scale-Varying Exploratory Analysis
Publication Year: 2007, Page(s):1161 - 1168
Cited by: Papers (25)We introduce a series of geographically weighted (GW) interactive graphics, or geowigs, and use them to explore spatial relationships at a range of scales. We visually encode information about geographic and statistical proximity and variation in novel ways through gw-choropleth maps, multivariate gw-boxplots, gw-shading and scalograms. The new graphic types reveal information... View full abstract»

Visualizing the History of Living Spaces
Publication Year: 2007, Page(s):1153 - 1160
Cited by: Papers (28)The technology available to building designers now makes it possible to monitor buildings on a very large scale. Video cameras and motion sensors are commonplace in practically every office space, and are slowly making their way into living spaces. The application of such technologies, in particular video cameras, while improving security, also violates privacy. On the other hand, motion sensors, ... View full abstract»

Legible Cities: Focus-Dependent Multi-Resolution Visualization of Urban Relationships
Publication Year: 2007, Page(s):1169 - 1175
Cited by: Papers (23)Numerous systems have been developed to display large collections of data for urban contexts; however, most have focused on layering of single dimensions of data and manual calculations to understand relationships within the urban environment. Furthermore, these systems often limit the user's perspectives on the data, thereby diminishing the user's spatial understanding of the viewing region. In t... View full abstract»

Interactive Visual Exploration of a Large Spatio-temporal Dataset: Reflections on a Geovisualization Mashup.
Publication Year: 2007, Page(s):1176 - 1183
Cited by: Papers (81) | Patents (1)Exploratory visual analysis is useful for the preliminary investigation of large structured, multifaceted spatio-temporal datasets. This process requires the selection and aggregation of records by time, space and attribute, the ability to transform data and the flexibility to apply appropriate visual encodings and interactions. We propose an approach inspired by geographical 'mashups' in which fr... View full abstract»

Hotmap: Looking at Geographic Attention
Publication Year: 2007, Page(s):1184 - 1191
Cited by: Papers (47) | Patents (3)Understanding how people use online maps allows data acquisition teams to concentrate their efforts on the portions of the map that are most seen by users. Online maps represent vast databases, and so it is insufficient to simply look at a list of the most-accessed URLs. Hotmap takes advantage of the design of a mapping system's imagery pyramid to superpose a heatmap of the log files over the orig... View full abstract»

VisLink: Revealing Relationships Amongst Visualizations
Publication Year: 2007, Page(s):1192 - 1199
Cited by: Papers (74) | Patents (2)We present VisLink, a method by which visualizations and the relationships between them can be interactively explored. VisLink readily generalizes to support multiple visualizations, empowers inter-representational queries, and enables the reuse of the spatial variables, thus supporting efficient information encoding and providing for powerful visualization bridging. Our approach uses multiple 2D ... View full abstract»

Visualization of Heterogeneous Data
Publication Year: 2007, Page(s):1200 - 1207
Cited by: Papers (16) | Patents (3)Both the resource description framework (RDF), used in the semantic web, and Maya Viz u-forms represent data as a graph of objects connected by labeled edges. Existing systems for flexible visualization of this kind of data require manual specification of the possible visualization roles for each data attribute. When the schema is large and unfamiliar, this requirement inhibits exploratory visuali... View full abstract»

Sequential Document Visualization
Publication Year: 2007, Page(s):1208 - 1215
Cited by: Papers (9)Documents and other categorical valued time series are often characterized by the frequencies of short range sequential patterns such as n-grams. This representation converts sequential data of varying lengths to high dimensional histogram vectors which are easily modeled by standard statistical models. Unfortunately, the histogram representation ignores most of the medium and long range sequentia... View full abstract»

Toward a Deeper Understanding of the Role of Interaction in Information Visualization
Publication Year: 2007, Page(s):1224 - 1231
Cited by: Papers (214) | Patents (2)Even though interaction is an important part of information visualization (Infovis), it has garnered a relatively low level of attention from the Infovis community. A few frameworks and taxonomies of Infovis interaction techniques exist, but they typically focus on low-level operations and do not address the variety of benefits interaction provides. After conducting an extensive review of Infovis ... View full abstract»

Animated Transitions in Statistical Data Graphics
Publication Year: 2007, Page(s):1240 - 1247
Cited by: Papers (103) | Patents (15)In this paper we investigate the effectiveness of animated transitions between common statistical data graphics such as bar charts, pie charts, and scatter plots. We extend theoretical models of data graphics to include such transitions, introducing a taxonomy of transition types. We then propose design principles for creating effective transitions and illustrate the application of these principle... View full abstract»

Browsing Zoomable Treemaps: Structure-Aware Multi-Scale Navigation Techniques
Publication Year: 2007, Page(s):1248 - 1253
Cited by: Papers (23)Treemaps provide an interesting solution for representing hierarchical data. However, most studies have mainly focused on layout algorithms and paid limited attention to the interaction with treemaps. This makes it difficult to explore large data sets and to get access to details, especially to those related to the leaves of the trees. We propose the notion of zoomable treemaps (ZTMs), an hybridiz... View full abstract»

Visualizing Causal Semantics Using Animations
Publication Year: 2007, Page(s):1254 - 1261
Cited by: Papers (6)Michotte's theory of ampliation suggests that causal relationships are perceived by objects animated under appropriate spatiotemporal conditions. We extend the theory of ampliation and propose that the immediate perception of complex causal relations is also dependent on a set of structural and temporal rules. We designed animated representations, based on Michotte's rules, for showing complex cau... View full abstract»

Spatialization Design: Comparing Points and Landscapes
Publication Year: 2007, Page(s):1262 - 1269
Cited by: Papers (16)Spatializations represent non-spatial data using a spatial layout similar to a map. We present an experiment comparing different visual representations of spatialized data, to determine which representations are best for a non-trivial search and point estimation task. Primarily, we compare point-based displays to 2D and 3D information landscapes. We also compare a colour (hue) scale to a grey (lig... View full abstract»

Weaving Versus Blending: a quantitative assessment of the information carrying capacities of two alternative methods for conveying multivariate data with color.
Publication Year: 2007, Page(s):1270 - 1277
Cited by: Papers (27)In many applications, it is important to understand the individual values of, and relationships between, multiple related scalar variables defined across a common domain. Several approaches have been proposed for representing data in these situations. In this paper we focus on strategies for the visualization of multivariate data that rely on color mixing. In particular, through a series of contro... View full abstract»
