This paper is a call to action for research and discussion on data visualization education. As visualization evolves and spreads through our professional and personal lives, we need to understand how to support and empower a broad and diverse community of learners in visualization. Data Visualization is a diverse and dynamic discipline that combines knowledge from different fields, is tailored to suit diverse audiences and contexts, and frequently incorporates tacit knowledge. This complex nature leads to a series of interrelated challenges for data visualization education. Driven by a lack of consolidated knowledge, overview, and orientation for visualization education, the 21 authors of this paper-educators and researchers in data visualization-identify and describe 19 challenges informed by our collective practical experience. We organize these challenges around seven themes People, Goals & Assessment, Environment, Motivation, Methods, Materials, and Change . Across these themes, we formulate 43 research questions to address these challenges. As part of our call to action, we then conclude with 5 cross-cutting opportunities and respective action items: embrace DIVERSITY+INCLUSION, build COMMUNITIES, conduct RESEARCH, act AGILE, and relish RESPONSIBILITY. We aim to inspire researchers, educators and learners to drive visualization education forward and discuss why, how, who and where we educate, as we learn to use visualization to address challenges across many scales and many domains in a rapidly changing world: viseducationchallenges.github.io.

Background: Postfracture acute pain is often inadequately managed in older adults. Mobile health (mHealth) technologies can offer opportunities for self-management of pain; however, insufficient apps exist for acute pain management after a fracture, and none are designed for an older adult population. Objective: This study aims to design, develop, and evaluate an mHealth app prototype using a human-centered design approach to support older adults in the self-management of postfracture acute pain. Methods: This study used a multidisciplinary and user-centered design approach. Overall, 7 stakeholders (ie, 1 clinician-researcher specialized in internal medicine, 2 user experience designers, 1 computer science researcher, 1 clinical research assistant researcher, and 2 pharmacists) from the project team, together with 355 external stakeholders, were involved throughout our user-centered development process that included surveys, requirement elicitation, participatory design workshops, mobile app design and development, mobile app content development, and usability testing. We completed this study in 3 phases. We analyzed data from prior surveys administered to 305 members of the Canadian Osteoporosis Patient Network and 34 health care professionals to identify requirements for designing a low-fidelity prototype. Next, we facilitated 4 participatory design workshops with 6 participants for feedback on content, presentation, and interaction with our proposed low-fidelity prototype. After analyzing the collected data using thematic analysis, we designed a medium-fidelity prototype. Finally, to evaluate our medium-fidelity prototype, we conducted usability tests with 10 participants. The results informed the design of our high-fidelity prototype. Throughout all the phases of this development study, we incorporated inputs from health professionals to ensure the accuracy and validity of the medical content in our prototypes. Results: We identified 3 categories of functionalities necessary to include in the design of our initial low-fidelity prototype: the need for support resources, diary entries, and access to educational materials. We then conducted a thematic analysis of the data collected in the design workshops, which revealed 4 themes: feedback on the user interface design and usability, requests for additional functionalities, feedback on medical guides and educational materials, and suggestions for additional medical content. On the basis of these results, we designed a medium-fidelity prototype. All the participants in the usability evaluation tests found the medium-fidelity prototype useful and easy to use. On the basis of the feedback and difficulties experienced by participants, we adjusted our design in preparation for the high-fidelity prototype. Conclusions: We designed, developed, and evaluated an mHealth app to support older adults in the self-management of pain after a fracture. The participants found our proposed prototype useful for managing acute pain and easy to interact with and navigate. Assessment of the clinical outcomes and long-term effects of our proposed mHealth app will be evaluated in the future.

Designing patient-collected health data visualizations to support communicating patient data during clinical visits is a challenging problem due to the heterogeneity of the parties involved: patients, healthcare providers, and healthcare systems. Designers must ensure that all parties’ needs are met. This complexity makes it challenging to find a definitive solution that can work for every individual. We have approached this research problem—communicating patient data during clinical visits—as a wicked problem. In this article, we outline how wicked problem characteristics apply to our research problem. We then describe the research methodologies we employed to explore the design space of individualized patient data visualization solutions. Lastly, we reflect on the insights and experiences we gained through this exploratory design process. We conclude with a call to action for researchers and visualization designers to consider patients’ and healthcare providers’ individualities when designing patient data visualizations.

Stroke is one of the leading causes of disability worldwide. The efficacy of stroke recovery is determined by various factors, including patient adherence to their rehabilitation program. Effective communication between healthcare providers and patients is crucial for promoting patients’ adherence to rehabilitation programs. Aiming to support patient-healthcare provider communication during inpatient stroke rehabilitation, we (1) conducted semi-structured interviews with healthcare providers with expertise in inpatient stroke recovery to extract design requirements for visualizing stroke recovery progress. Using these design requirements, we (2) designed a data visualization tool representing stroke recovery. We (3) sought feedback on the visualization designs from healthcare providers and patients and integrated their feedback into the designs. Informed by the results of our studies, we provided several considerations for designing future visualization tools for patients and providers to communicate during inpatient stroke rehabilitation.

Aim: Sexual dysfunction is an important, and often overlooked, sequela of rectal cancer treatment with significant implications for patients' quality of life. The aim of this study was to explore patients' information needs regarding sexual health after rectal cancer treatment and their experiences accessing information on sexual dysfunction throughout the cancer care continuum. The secondary aim was to explore surgeons' perspectives on patients' information needs and gain insight into their experiences providing information on sexual health following rectal cancer surgery.Method: A qualitative study was conducted using semistructured interviews with 10 rectal cancer survivors and six colorectal surgeons from a Canadian tertiary care institution. Transcribed interviews were coded independently by two researchers and thematic analysis was performed.Results: Analysis of patient interviews revealed that patients had limited knowledge of sexual dysfunction symptoms following rectal cancer treatment and received inadequate information on sexual dysfunction from their treating medical team. Patients expressed the desire to receive information on sexual dysfunction in different formats, especially before the start of treatment. The surgeon interviews revealed that colorectal surgeons faced challenges when informing patients about sexual dysfunction. Surgeons did not routinely provide information on sexual dysfunction to all patients; however, they felt that patients should receive high‐quality information on sexual dysfunction, both before and after treatment.Conclusion: Patients' information needs related to sexual dysfunction after rectal cancer treatment were inadequately met. High‐quality informational resources are needed to facilitate communication between patients and physicians and improve patients' understanding of sexual dysfunction.
