Relational databases provide significant flexibility to organize, store, and manipulate an infinite variety of complex data collections. This flexibility is enabled by the concept of relational data schemas, which allow data owners to easily design custom databases according to their unique needs. However, user interfaces and information visualizations for accessing and utilizing databases have...

Microblogging services provide a novel and popular communication scheme for Web users to share information and express opinions by publishing short posts, which usually reflect the users’ daily life. We can thus model the users’ daily status and interests according to their posts. Because of the high complexity and the large amount of the content of the microblog users’ posts, it is necessary t...

The use of visualization to explore and understand data is often partitioned into two areas, scientific visualization in which the data sets are typically derived from measurements or simulations grounded in physical space, and information visualization where data sets are defined over abstract spaces. Although there are certain pragmatic differences based on the way that visualization is used,...

In this paper we tackle the main problem presented by the majority of Information Visualization techniques, that is, the limited number of data items that can be visualized simultaneously. Our approach proposes an innovative and interactive systematization that can augment the potential for data presentation by utilizing multiple views. These multiple presentation views are kept linked accordin...

This paper summarizes the literature on visualisation and information visualisation and provides a broad view of available systems and techniques. The paper also argues that the use of visuals can help conveying information, and that can be an advantage to the use of visualisation and information visualisation to support information management.

DOI: 10.1057/palgrave/ivs/9500009 Welcome to Information Visualization! I am delighted to be able to introduce to you the first issue of the peer-reviewed international journal dedicated to the research and practice of information visualization. The new journal will cover a variety of aspects of information visualization, ranging from fundamental research to practical applications. Information ...

This is a short introduction to information visualisation, which is increasingly important in many fields as information expands faster than our ability to comprehend it. Visualisation makes data easier to understand through direct sensory experience (usually visual), as opposed to more linguistic/logical reasoning. This chapter examines reasons for using information visualisation both for prof...

We conducted a within-subject experiment involving 13 participants that empirically explore how two different models of story delivery involving information visualization influence audience-constructed narratives. The first model involves a speaker using visualization software to communicate a direct narrative, while the second involves constructing a story by interactively exploring visualizat...

Data visualization is an important tool for discovering patterns in the data. Finding interesting visualizations can be however a difficult task if there are many possible ways to visualize the data. In this paper we present the VizRank method that can estimate visualization interestingness. The method can be applied on a number of visualization techniques and can automatically identify the mos...

The paper considers the relationship of information visualization tools to the data mining process. The types of structures that may be of interest to data mining experts in data sets are outlined. The performance of a particular visualization technique in revealing those structures and supporting the subsequent steps in the process needs to be based on a number of criteria. The criteria for pe...
