Nathan Yau's Flowing Data [https://flowingdata.com/] website was one of the first data visualization websites I discovered in my own data journey. With his new book, Visualize This [https://amzn.to/3VfRWhl], now out, I thought it would be a great opportunity to talk with Nathan about his work, his book, and how his own approach to data has evolved over the last several years.

The new edition of Visualize This [https://amzn.to/3VfRWhl] enriches readers with modern techniques and examples, focusing on effectively learning data visualization by exploring different data types and designing for clear communication, even for those without a formal design background. Nathan emphasizes the necessity of audience-appropriate visualizations and the selection of suitable tools, all of which have changed and evolved since the first edition of the book was published in 2011.

We obviously talk about the latest book in this episode of the podcast, including Nathan's process for creating graphics (a lot of R and Adobe Illustrator), his professional growth from a statistics PhD program to embracing full-time visualization work. We discuss the nuances of handling feedback, the differentiation between misinformation and subjective interpretation, and the significance of constructive criticism. We also touch on challenges for newcomers in the field, the need for clearer communication of uncertainty, and the potential of virtual and augmented reality.

Evolving Data Visualization: Crafting the Second Edition of Visualize This with Nathan Yau

Welcome to a solo episode! In this special episode of the podcast, I talk about the recen Tableau Customer conference in San Diego, which drew over 9,000 participants. I reflect on various aspects of the conference, including its diverse sessions that ranged from showcasing new Tableau features and case studies to hands-on workshops and discussions on data visualization beyond Tableau. I was a presenter at TC and presented my work on the Urban Institute's Do No Harm Project.

My review of the conference focuses just on the positives of the conference—the upcoming features in Tableau, such as allowing Tableau Public users to save work their locally, as well as some thoughts on why I—who is not a huge Tableau user—actually attends the conference. I also discuss a few of the sessions I attended, including hands-on sessions and games in Tableau.

Topics Discussed

 * Conference Overview: A recap of the Tableau Conference, highlighting its scale with over 9,000 participants and the variety of sessions that catered to both seasoned data analysts and newcomers to the field.
 * Tableau's New Features. Significant updates to Tableau, including the ability for Tableau Public users to save work locally – a feature that potentially redefines the need for Tableau Desktop licenses. I also talk about the introduction of customizable themes, Google Fonts integration, VIS Extensions, and the leaps in AI and real-time data integration within Tableau.
 * Community and Networking: I reflect on the value of the community that Tableau fosters, especially through networking opportunities that are more crucial than ever in the post-pandemic era.

Insights from the Tableau Conference in San Diego

You know Enrico Bertini, right? Writer, teacher, co-host of the Data Stories podcast, Enrico does it all. Now at Northeastern University, I invited Enrico to the show to talk about his research, great Substack newsletter, and for views on the evolving landscape of data visualization on social media. In our discussion, Enrico emphasized the significance of interdisciplinary collaboration at Northeastern University. He has some concerns about the current state of visualization theory and tools and talks about his ideas around "critical data thinking" as a crucial way of thinking about data visualization, highlighting the challenges of data accuracy and interpretation. We also talk about Enrico's teaching methods to help students improve their data interpretation and data visualization skills. Enrico and I share some of the same feelings about the shifts in social media use in the dataviz community, and how it has led to a loss in diverse intellectual exchanges, underscoring the importance of finding new ways to foster community engagement and creativity, including through writing platforms like Substack and LinkedIn.

Topics Discussed

 * The Current State of Visualization Theories and Tools: Enrico critiques the prevalent theories and tools in data visualization, calling for a more systematic and thoughtful approach to both creating and interpreting visual data.
 * Challenges of Presenting Accurate Data: Our conversation delves into the difficulties faced in presenting precise and accurate data, especially highlighted during the COVID-19 pandemic, and how these challenges have impacted the field.
 * Impact of Social Media Platform Shifts: A significant focus of our conversation is on the changing landscape of social media platforms, particularly the decline of Twitter as a crucial space for professional exchanges within the data visualization community.
 * Reflections Prompted by the Pandemic: Enrico reflects on the pandemic's role in helping him reevaluate his work and teaching practices, which is a helpful insight into how his creativity has changed and adapted over the last few years.
 * The Role of Newsletters in Idea Refinement and Audience Connection: Enrico shares insights into how newsletters have become a pivotal tool for refining ideas and connecting with a diverse audience, including students from various disciplines, fostering a richer, more engaged community.
 * Interdisciplinary Collaboration for Innovation: Highlighting the value of interdisciplinary collaboration, especially at Northeastern, this week's episode showcases how interactions between computer science engineering students and design peers, as well as varied problem-solving approaches from faculty members, can lead to fresh insights and propel the field forward.
