Scientists often explore and analyze large-scale scientific simulation data by leveraging 2-D and 3-D visualizations. The data and tasks can be complex and therefore best supported using myriad display technologies, from mobile devices to large high-resolution display walls to virtual reality headsets. Using a simulation of neuron connections in the human brain provided for the 2023ieee Scientific visualization Contest, we present our work leveraging various web technologies to create a multiplatform scientific visualization application. Users can spread visualization and interaction across multiple devices to support flexible user interfaces and both colocated and remote collaboration. Drawing inspiration from responsive web design principles, this work demonstrates that a single codebase can be adapted to develop scientific visualization applications that operate everywhere.

Debugging programs is one of the most challenging and time consuming parts of programming. datascience scripts present additional challenges as debugging often centers around more exploratory tasks, such as understanding the differences between results under different parameter settings. In fact, a common exploratory debugging practice is to run, modify, and re-run a script to observe the effects of the modification. Analysts perform this process frequently as they explore different settings and algorithms in their analysis. However, traditional debugging methods are not well suited to comparing across multiple executions of a script. They often require maintaining two instances of the debugging method and making manual, serial comparisons of program values. To address this gap, we present Aardvark, a comparative trace-based debugging method for identifying and visualizing the differences between two executions of data analysis scripts. Aardvark traces two consecutive instances of an analysis script, identifies the differences between them, and presents them through comparative visualizations. We present a prototype implementation in Python as well as an extension to support scripts in Jupyter notebooks. Finally, to demonstrate Aardvark, we provide two usage scenarios on real world analysis scripts.

Understanding how local environments influence individual behaviors, such as voting patterns or suicidal tendencies, is crucial in social science to reveal and reduce spatial disparities and promote social well-being. With the increasing availability of large-scale individual-level census data, new analytical opportunities arise for social scientists to explore human behaviors (e.g., political engagement) among social groups at a fine-grained level. However, traditional statistical methods mostly focus on global, aggregated spatial correlations, which are limited to understanding and comparing the impact of local environments (e.g., neighborhoods) on human behaviors among social groups. In this study, we introduce a new analytical framework for analyzing multi-variate neighborhood effects between social groups. We then propose NeighViz, an interactive visual analytics system that helps social scientists explore, understand, and verify the influence of neighborhood effects on human behaviors. Finally, we use a case study to illustrate the effectiveness and usability of our system.

Verifiable data streaming (vds) protocols enable end users with limited storage space to continuously stream data items to an untrusted cloud server, while preserving the capacity of verifying the integrity of those retrieved data items for downstream tasks. Although there has been plenty of research around the construction of vds, we observe that they all focus on the scenario of single-user. When deploying these vds protocols into more common applications that involve multiple users' data (e.g., network data monitoring and stock trends analysis), the size of the proof used to prove the integrity of retrieved data items grows linearly with the number of involved users. This would bring tremendous communication overhead, especially for lightweight users. To this end, we initiate the study of vds protocols that are suitable for multi-user (or cross-user) setting. Specifically, we first introduce a new primitive called aggregatable chameleon vector commitment (ACVC) that allows to aggregate multiple proofs from different commitments into a single proof. Then, based on ACVC, we present a communication-efficient vds protocol for the multi-user setting. That is, when querying data items from multiple users, the size of corresponding proof is constant and independent of the number of involved users. Theoretical analysis indicates that the proposed vds protocol outperforms previous vds protocols in terms of communication overhead. We also implement the proposed ACVC, and conduct extensive experiments to demonstrate its practicability.

visualization techniques are useful in the analysis and insight generation for applications in computing in science and engineering. In this article, we describe the importance of visualization to a digital twin (DT), a virtual representation of a physical object, process or system that can be applied for different tasks, such as data-driven simulation, analysis or monitoring. We illustrate tasks in DTs and give examples of how visualization techniques can be applied for DTs in different application areas.

As the professional field of datavisualization grows, so does the importance of preparing students effectively for the demands of real-world practice. Computing education has historically sought to teach and evaluate abstract knowledge (e.g., theories, principles, guidelines, design patterns) and the application of such knowledge to given problems. However, situations faced in professional practice are often messy, dynamic, and uncertain, and do not lend themselves well to the clear and direct application of such knowledge. This leaves a gap between the knowledge learned in the classroom and what is required for skillful practice in professional settings. In this paper, I discuss some historical reasons for this dominant pedagogical perspective, some of the core features of professional practice that are not typically taught in classrooms, and ways in which datavisualization design can be taught to be more resonant with the experience of professional practice.

Mathematical optimization is the process of determining the set of globally or locally optimal parameters in a finite or infinite search space. It has been extensively employed in the research areas of computer science, engineering, operations research, and economics. The application of mathematical optimization has also been extended to datavisualization, where it can enhance data processing, structure visualization, and facilitate exploration. However, the current state of summarization in the application of mathematical optimization in datavisualization remains inadequate. In this article, we review and classify the existing techniques for advanced mathematical optimization in the fields of datavisualization and visual analytics. The classification is conducted based on a classical visualization pipeline, including data enhancement and transformation, representation and rendering, as well as interactive exploration and analysis. We also discuss various mathematical optimization models and their solution methods to help readers gain a better understanding of the relationship among models, visualization, and application scenarios. We additionally provide an online exploration demo, which could enable users to interactively find relevant articles. Based on the limitations and potential trends revealed in the existing literature, we define future challenges in the cross-disciplinary of mathematical optimization and datavisualization.

While data scientists pursue new extremes of high-dimensional data, and datavisualization professionals attempt to visualize within that space, Nathan Selikoff's work suggested a unique perspective on relationship among complexity, higher dimensions, and sensing what otherwise cannot be sensed. His long-tailed pursuit of visualizing complexity piqued our interest as we interviewed him for this article.
