Visualization has been deemed a useful technique by researchers and practitioners, alike, leaving a trail of arguments behind that reason why visualization works. In addition, examples of misleading usages of visualizations in information communication have occasionally been pointed out. Thus, to contribute to the fundamental understanding of our discipline, we require a comprehensive collection of arguments on "why visualize?" (or "why not?"), untangling the rationale behind positive and negative viewpoints. In this paper, we report a theoretical study to understand the underlying reasons of various arguments; their relationships (e.g., built-on, and conflict); and their respective dependencies on tasks, users, and data. We curated an argumentative network based on a collection of arguments from various fields, including information visualization, cognitive science, psychology, statistics, philosophy, and others. Our work proposes several categorizations for the arguments, and makes their relations explicit. We contribute the first comprehensive and systematic theoretical study of the arguments on visualization. Thereby, we provide a roadmap towards building a foundation for visualization theory and empirical research as well as for practical application in the critique and design of visualizations. In addition, we provide our argumentation network and argument collection online at https://whyvis.dbvis.de, supported by an interactive visualization.

Standard models for network meta-analysis simultaneously estimate multiple relative treatment effects. In practice, after estimation, these multiple estimates usually pass through a formal or informal...
We investigate the effectiveness of network attack strategies when the attacker has only imperfect information about the network. While most existing network attack strategies assume complete knowledg...
The use of network control theory to analyze the organization of white matter fibers in the human brain has the potential to enable mechanistic theories of cognition, and to inform the development of ...
Arguments in Texas raise questions about the ACA's fate as enrollment holds steady and new state reinsurance waivers are approved.
Transcranial direct current stimulation (tDCS) is routinely used in basic and clinical research, but its efficacy has been challenged on a methodological, statistical and technical basis recently. The...
The proposed project seeks to create a California early psychosis network using a core assessment battery of valid, low burden measures and mHealth technology platform to collect client-le...
Heroin addiction is a serious problem and the relapse rate of existing treatment methods is extremely high. Recently, international journals such as Science reported that repetitive transc...
White matter hyperintensity (WMH) has been found to be related with cognitive and emotional dysfunction. A presumed mechanism is that WMH disrupts the structural connectivity within a larg...
Relapse is the most serious problem in alcoholism treatment. The overall aim of the present study was to determine if a treatment directed at changing the patient's social network, from on...
Several breast diseases can complicate breastfeeding : 4% of women develop a mastitis and 1% develop an abscess. The study deals with cases of breast abscess that have been treated accord...
A method of detecting gene mutation by mixing PCR-amplified mutant and wild-type DNA followed by denaturation and reannealing. The resultant products are resolved by gel electrophoresis, with single base substitutions detectable under optimal electrophoretic conditions and gel formulations. Large base pair mismatches may also be analyzed by using electron microscopy to visualize heteroduplex regions.
