It is widely recognized that data visualization may be a powerful instrument for exploratory analysis. In order to fulfill this claim, visualization software must be carefully designed taking into account two principal aspects: characteristics of the data to be visualized and the exploratory tasks to be supported. The tasks that may potentially arise in data exploration are, in their turn, depe...

The importance of information visualization as a means of transforming data into visual, understandable form is now embraced across university campuses and research institutes worldwide. Yet the role of designers in this field of activity is often overlooked by the dominant scientific and technological interests in data visualization, and a corporate culture reliant on off-the-shelf visualizati...

More and more, the products of statistical analysis that we encounter in our everyday lives come in the form of data visualizations. Visualizations have the advantage of being easier to interpret for many people, but they also give the impression of being a form of absolute truth. As with any presentation method, though, visualizations can be manipulated by their creators to show the story they...

we reported a 35 year old breast cancer patient who was referred to our nuclear medicine department for sentinel node mapping. she was planned to undergo mastectomy and lymphatic mapping. a dose of tc-99m phytate was injection in the peri-areolar region in an intra-dermal fashion. two hours post-injection no sentinel node was visible in the axilla. due to a high liver uptake, inadvertent intra-...

We revisit the design space of visualizations aiming at identifying and relating its components. In this sense, we establish a model to examine the process through which visualizations become expressive for users. This model has leaded us to a taxonomy oriented to the human visual perception, a conceptualization that provides natural criteria in order to delineate a novel understanding for the ...

A common issue in cluster analysis is that there is no single correct answer to the number of clusters, since cluster analysis involves human subjective judgement. Interactive visualization is one of the methods where users can decide a proper clustering parameters. In this paper, a new clustering approach called CDCS (Categorical Data Clustering with Subjective factors) is introduced, where a ...

This paper describes a novel and efficient visualization technique intended for hierarchical-temporal data using a tree-ring like layout. Temporal hierarchies appear in numerous fields such as genealogy, evolution taxonomies or time lines. In many cases, state-of-the-art static diagrams are produced in these fields. By using several information visualization strategies, such as focus + context,...

INTRODUCTION Recently, data visualization has received a great deal of attention. Furthermore, the need for better information visualization tools is widely recognized [1], [2]. One of the main reasons for better information visualization tools is the limitation of the human cognitive process. Specifically, humans have difficulty extracting meaningful information from large volumes of data [2]....

—In this survey project, the data visualization and information visualization in the sensor network are the main topics. Base on the literature review in related topics, this project report will summarize some of the encoding methods with the framework they proposed. The main section of this paper will be separated into three sections: visualization in properties and problems on sensor network,...

Our ongoing work aims to better understand the relationship between visual marks and data encodings that comprise innovative data visualizations. By innovative, we refer to data visualizations that in part extend or deviate from conventional visualization techniques. Authors of these types of visualizations engage and inform their audience by incorporating novel data-bound compositions. In our ...
