Welcome to the Season 11 Finale of the PolicyViz Podcast! I’m ready for a summer break and am super excited to close the season talking with Shirly Wu—data visualization artist, technologist, and community thought leader. We talk about Shirley’s journey from creating vibrant, web-based data visualizations to developing physical, multi-sensory data art. Shirley shares what she learned during her recent graduate studies in art and technology, her reflections on data, emotion, and the role of art, and the ideas behind her widely discussed blog series on the state of innovation in the data visualization field. We also discuss how the pandemic reshaped our community, the challenge of maintaining creative joy, and the importance of making space for both functional and expressive data storytelling. From Tokyo to San Francisco, Shirley’s work bridges client projects and immersive art experiences, all grounded in data.

In this week’s episode of the PolicyViz Podcast, I am reposting my 2015 interview with Edward Tufte, one of the pioneers of data visualization and author of seminal books like The Visual Display of Quantitative Information. At the time, Tufte was a well-known and hugely influential figure in the field. Over time, his influence has waned, and I find that fewer and fewer people are aware of his work and his impacts on the field of data visualization. Before closing up this season next week, I thought it worth looking back to this interview and listen to Tufte as he reflects on analytical thinking, visual reasoning, and the intersection of art and science. We discussed his sculpture work, the evolution of information design, the power of high-resolution displays, and the importance of clarity and excellence in presenting data. The conversation spans from Tufte’s early teaching days to his vision for the future of data communication, offering a rich mix of philosophy, design, and practical insight.

My friend Andy Kirk joins the show to reflect on the changing landscape of data visualization. We discuss the evolution of tools like Tableau and Flourish, the dispersion of social media communities, and how, how AI is reshaping workflows and data visualization. Andy shares insights from his freelance experience, the challenges of teaching data preparation, and his measured take on critique and awards in the field. This episode captures a moment of introspection in data viz—where progress is evident, but big questions remain.

In this episode of the PolicyViz Podcast, I have the pleasure of talking with Harsha Mallajosyula, Director of Data at the Black Wealth Data Center, about the center’s mission to provide accessible, high-quality data on racial wealth equity in the United States. Harsha shares insights into how the center aggregates and cleans data from public and private sources, making it easier for policymakers, researchers, and advocates to understand and address racial wealth disparities. He discusses the challenges of merging datasets with different racial classifications, the importance of data transparency, and the center’s shift toward more intuitive, mobile-friendly visualization tools. Harsha also highlights the future of the Black Wealth Data Center, including the use of AI and machine learning for data improvement, expanding user research, and developing new tools for deeper insights.

In this episode of the PolicyViz Podcast, I speak with Yanni Loukissas, an Associate Professor at Georgia Tech, about the importance of context in working with data. Yanni argues that data are not universal but local—shaped by their origins, environments, and the intentions of those who collect them. Our conversation dives into how this perspective challenges dominant narratives in data science, particularly the assumption that datasets are neutral or universally applicable. We also discuss how design and storytelling can play a role in exposing the situated nature of data and how educators and practitioners can better teach and communicate these ideas.
