Dan and his colleagues have developed real-time visualizations of transactions in the “blockchain,” the public ledger used by Bitcoin to create and document transactions. The visualizations are displayed in their Data Observatory, a beautiful, high-resolution, 64-screen distributed rendering of a cluster with a canvas of 132M pixels. On the show we discuss Bitcoin and how it works, the visualizations Dan and his colleagues have developed, and what can be done next to visualize cryptocurrencies.

Download: MP3 Audio55 MB MPEG-4 AAC Audio43 MB In this episode, we have artist and sculptor Adrien Segal on the show to talk about her beautiful, thoughtful, and engaging data sculptures. Adrien is based in Oakland, California. Her work has been exhibited internationally in galleries and museums around the world. On the show, we talk about some her great artwork, including Tidal Datum, which depicts tidal charts from the National Oceanic and Atmospheric Administration (NOAA), and Grewingk Glacier, an ice sculpture depicting “the shape of the terminus of Grewingk Glacier as it has receded over 150 years time.” We also talk about the process Adrien follows for her sculpture production, her thinking about work in physical versus digital materials, the boundaries between art and science, and how listeners might experiment with their own data sculptures! Enjoy the show! A minor correction to the show: It takes 29 days for the moon to go around the Earth, not the Sun.  Data Stories is brought to you by Qlik.

We have two of the project researchers on the show, Basak Alper from NASA JPL and Nathalie Riche from Microsoft Research, to tell us all about it. On the show we talk about the inception of the project, the findings they discovered by both talking to teachers and analyzing visualization materials used in schools, and the “C’est la Vis” prototype they have developed as a way to teach visualization to kids.

Nicky has developed a whole set of projects over the years, including the popular “Parable Of The Polygons,” which describes how small biases can lead to segregation, and “To Build A Better Ballot,” which demonstrates the impact of various types of voting ballots. On the show we talk about both of these projects in detail, the definition of explorable explanations, how simulation and interaction might play a role in visualization, and the future of this kind of project.

You can contribute just the cost of one or two lattes for each episode we publish every two weeks. *** In this episode we have famous cartoonist and comics theorist Scott McCloud. Scott wrote the popular books Understanding Comics (1993), Reinventing Comics (2000), and Making Comics (2006), which explain the theory and practice behind making comics and telling stories visually. Scott has gained a big following among data visualization designers over the years. By following the strategies he describes in his books, one can develop rich narratives that are useful in data visualization as well as comics. On the show we talk about his books, the power of frames, Scott’s definition of story, virtual reality, and what people in vis can learn from comic artists.

Download: MP3 Audio21 MB MPEG-4 AAC Audio17 MB [If you enjoy the show, consider supporting us on Patreon! You pay a small fee for each episode we publish.] In this episode, we have Michael Correll and Jeff Heer from the University of Washington to talk about a novel visualization technique they developed called “Surprise Maps”: a new kind of map which visualizes what is most surprising in a dataset. Using their own words: “The idea behind Surprise Maps is that when we look at data, we often have various models of expectation: things we expect to see, or not see, in our data. If we have these models, we can also measure deviation or difference from these models. This deviation is the unexpected, the data that surprise us.” On the show we talk about how they came up with the idea for Surprise Maps, how they work, and potential applications and extensions for the technique.

Download: MP3 Audio45 MB MPEG-4 AAC Audio35 MB In this episode we are joined by Kim Rees and Steph Hay of Capital One. You may have heard the big news that Capital One recently decided to hire Kim Rees (formerly of Periscopic) as their Head of Data Visualization. It’s great to see such a big company hire a high caliber data viz professional like Kim and create a position with this name. Things seems to be moving in the right direction for viz after all! Curious about what this news might mean for the industry, we invited Kim and her new boss Steph — Head of Content, Culture, and AI Design at Capital One — to learn about their plans. This episode is a nice counterpoint to the episode we recently recorded with Elijah Meeks, which centered on the issues that data visualization professionals are facing in the industry. Now, with Kim and Steph we talk about the decision to create this position, the value Capital One sees in visualization, and how they plan to scale visualization to a company of 40,000 employees. Enjoy the show! We’re collecting listener questions, ideas, and suggestions about Data Stories for our upcoming 100th episode.
