In this work, we systematically identify and curate the task-based challenges of comparative studies by reviewing existing visualization literature on the topic. Furthermore, for each of the presented challenges we discuss the potential threats to validity for a comparative study. The challenges discussed in this paper are further backed by evidence identified in a detailed survey of comparative tree visualization studies.

CerebroVis is a novel network visualization tool which assists in diagnosis cerebrovascular abnormalities like stenosis and aneurysms. We found that CerebroVis improves the identification of cerebrovascular abnormalities in the brain over existing 3D MRA visualization.

In a crowdsourced experiment, we measured the effect of glyph design on an everyday task of categorization. We found that abstract glyphs are more accurate compared to anthropomorphic glyphs in a categorization experiment.

Multi-faceted data, such as a photo’s location, timestamp, and content, are difficult to navigate, particularly when a user has incomplete knowledge of the data, such as when the date of a photo is unknown. We present Picture Penguin, a novel personal photo navigation system that enables search and filtering through linked and combined views of temporal, geospatial, and photo content information. Picture Penguin scales to large photo collections andreduces complexity through clustering and data summarization techniques, and runs as both a mobile and a desktop application.

The Network Infrastructure of computer-based business is expanding every day. Consequently, monitoring and cyber-fencing of these massive networks is a growing concern within organizations. We developed a visualization tool which assists organizations to segment their network, write security policies and monitor network.
