    Mike "SullyDawg" Sullivan: Explaining Trillion-Dollar Budgets with Solo Cups

    In this week’s episode of the show, I talk with Mike "SullyDawg" Sullivan, the viral creator behind the cup pyramid videos that turn massive federal budget numbers into something you can actually see. Mike spent decades as a teacher and coach before a bike ride inspired his first video stacking Solo cups to explain government spending — and it took off almost overnight. We dig into why three-dimensional scale succeeds where bar charts and line graphs fail, how he sources and cross-checks the data behind every video, and the four-part formula he swears by: topic, data, energy, and visual. Mike also opens up about the physical work of stacking thousands of cups in his garage, the unpredictable swings of the social media algorithms, and what’s next for his growing platform. It’s a fun, thoughtful conversation about making enormous numbers finally make sense. Subscribe to this podcast.

    My Favorite Graphs: Stronger Together from The New York Times

    In this My Favorite Graphs episode, I revisit a 2016 New York Times visualization comparing the convention speeches of Donald Trump and Hillary Clinton. I explain why highlighting phrases across miniature pages can reveal themes in qualitative data that word counts and bar charts can miss. I share how I have used a simple version of this technique in my own work and discuss tools for creating similar views. Alicia contributes a voice note about the project's development, including the highlighted Google Docs behind the finished graphics. I also discuss how pairing an overview with example quotes can help readers see the broader context of an interview, focus group, or speech. Subscribe to this podcast.

    Playfair, Power, and the People Behind the Data: Lauren Klein on Data by Design

    Lauren Klein joins me to talk about her new book, Data by Design, co-authored with a team of student collaborators. Over more than a decade of work, Lauren set out to place the history of data visualization in its full historical and political context, going well beyond the familiar “great men” narrative of Playfair and Snow. We talk about how she chose which historical visualizations to feature and redesign, the ethical questions that come up when working with data about the transatlantic slave trade and Indigenous mapping, and what it actually took to track down high-resolution scans of centuries-old charts. Lauren also shares what she wants readers, especially working data visualization designers, to take away: that visualization is only as powerful as how, and by whom, it's put to use.

    My Favorite Graphs: The Guardian's "Bussed Out"

    This week I kick off a new series on the show: My Favorite Graphs. I’m going to walk through the projects that shaped how I think about data visualization, data communication, and data storytelling. I'm starting with the Guardian's “Bussed Out: How America Moves Its Homeless,” published in December 2017, an 18-month investigation into the one-way bus tickets that US cities hand out to homeless people. There’s a special treat at the end too! My Favorite Graph: Bussed Out Subscribe to this podcast. Follow this show and everything dataviz on Instagram, LinkedIn, Substack, X, and YouTube.

    What Data Communicators Can Learn from Speech-Language Pathology

    In this very special episode of the podcast, I talk with my wife, Lauren Schwabish, a speech-language pathologist who helps adults recover communication after stroke, traumatic brain injury, and other neurological conditions. We discuss person-centered care, translating medical jargon into plain language for patients and families, and the visual tools and assistive technology Lauren builds to help people with aphasia communicate — with real lessons for anyone designing data visualizations, dashboards, or reports for a broad audience.

    New Season, New Format: Live Shows, Accessibility, and My Favorite Dataviz

    Welcome back to Season 13 of the PolicyViz Podcast! In this quick solo kickoff, I walk you through everything I have planned this season, from a full episode on accessibility in data communication to a brand-new weekly series where I talk through some of my favorite data visualizations from the last 15 years. I'll also tell you about my very first live podcast recording, happening in November in Boston as part of the IEEE VIS Conference and the new Cluster Practitioner Summit I'm co-organizing. Along the way I'll be expanding my YouTube content around Flourish, Excel, and PowerPoint, including how I'm using AI tools like Claude and Copilot in my own workflow. It's shaping up to be a busy, lucky Season 13, and I'm so glad you're along for the ride. Subscribe to this podcast.

    The Math Behind Beautiful Color: David Aerne on Building Open-Source Color Tools

    Welcome to the final episode of Season #12 of the PolicyViz Podcast! Thanks so much for checking out the show this season and I hope you enjoy your summer. I’ll be back this fall with more great episodes. On this episode of the show, I’m joined by David Aerne, a freelance developer and designer based in Zurich who has spent years building a remarkable collection of open-source color tools. We dig into the difference between color models, color spaces, and gamuts, and David explains why thinking about color in three dimensions—like navigating a cylinder—can make choosing palettes so much more intuitive. We talk through several of his projects, including Color Names (a curated list of nearly 32,000 community-contributed color names), Rampensau for generating color ramps, and the playful RYB-inspired explainer that simulates how physical, “printy” colors look on screen. David shares his philosophy that we should integrate the systems that generate colors into our work, rather than freezing a static palette and losing the creativity along the way. Whether you build dashboards, design slides, or just love playing with color, this conversation will change how you think about picking your next palette.

    From Homework to Portfolio: NYC Open Data in the Classroom

    Welcome back to the show! In this week’s episode, I chat with Christian Martinez, a faculty member at Brooklyn College and several other CUNY schools, and Shannon Joyce, a newly minted master’s graduate in psychological research—who, as we note at the top, literally graduated the day before we recorded. Christian shares how he redesigned his graduate stats and R course around NYC Open Data, building what he calls an “accidental author” process that transforms students’ weekly homework into portfolio books and, ultimately, chapters in a published student gallery. Shannon walks us through her own project exploring the relationship between mold complaints and domestic violence rates in New York City, and reflects on what it means to learn to code by asking questions you actually care about. We also dig into the NYC Open Data R package Christian and his students built together—now streamlined from 40 functions down to three and approaching 2,000 installs—and close with a lively conversation about whether open data skews too negative and what a truly positive city dataset might look like.
