The Future of America's Data: Policy, Risk, and Resilience with Denice Ross
<p>In this episode, I talk with Denice Ross about the fragile state of federal data and her new work at DataIndex. We discuss how the removal, alteration, or disruption of federal data collections and data products affects research, policymaking, businesses, and everyday life. Denice explains the vision behind DataIndex and EssentialData, which monitor data risks, highlight data dependencies, and help users recognize how federal data benefit society. We also explore the roles of private-sector data, civic tech efforts, and public advocacy in building a more resilient national data infrastructure. It’s a fascinating look at what’s at stake when...
Before & After: Inside the New Book from the Storytelling with Data Team
<p>In this episode, I’m joined by Cole Nussbaumer Knaflic and Mike Cisneros from Storytelling with Data to talk about their new book, Before & After. We dig into where the examples came from, how they selected and refined real client work, and why the book focuses so heavily on process rather than rules or templates. We also reflect on how the data visualization field has evolved over the past decade—from best practices and chart types to iteration, audience empathy, and real-world constraints. Along the way, we talk about teaching data viz, common pitfalls, and why there’s no such t...
Radical Cartography: What Maps Show, What They Hide, and Why It Matters
<p>In this episode, I sit down with Bill Rankin, historian of science at Yale and author of Radical Cartography, to unpack what maps really do beyond simply showing data. We talk about why mapping is an act of representation with real consequences, how common techniques like choropleths and cartograms shape what we see—and what we miss—and why there’s no single “correct” way to visualize the world. Bill shares how his background in architecture influences his approach to mapping as drawing and world-making, not coding or dashboards. We also dig into static versus interactive maps, accessibility, and why starti...
Why Federal Statistics Matter: Rob Santos on Trust, Data Integrity, and the Future of the Census

The Future of Dashboards, Data Apps, and AI with Plotly's Chris Parmer
<p>In this week’s episode, I talk with Chris Parmer, co-founder of Plotly, about how the company is integrating AI into the next generation of data visualization and analytics tools. Chris walks me through the thinking behind Plotly Studio, their new AI-native environment where natural language prompts generate real, auditable code for charts, dashboards, and data apps. We discuss how this approach reduces bottlenecks for data teams, empowers non-technical users, and reshapes the role of the data visualization expert. We also dive into the limits of public dashboards, the rise of generative interfaces, and what a future of AI-driven ex...
Beyond the Visual: How Tactile Maps Expand Data Accessibility
<p>In this week’s episode, I welcome Jakub Wabiński and Vincent van Altena to the show to talk about their new book, Tactile Mapping. We explore how tactile and multisensory design can make maps—and data—more accessible for people with visual impairments and beyond. Jakub and Vincent share insights into how tactile maps are designed, tested, and used in real-world settings like museums and public spaces. We also discuss user-centered design, the challenges of scaling inclusive practices, and how tactile mapping can help everyone better understand and navigate the world around them.</p><p>Keywords: Jakub Wabiński, Vin...
