This episode we have Dan McGinn from Imperial College in London on the show to talk about visualizing Bitcoin data. 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.
Enjoy the show!

Data design systems and styleguides are currently a huge trend in the data design world. Moritz is joined by Gabrielle Mérite and Alan Wilson and together we exchange experiences in this emerging space, from designing dataviz components as part of Adobe Spectrum, the styleguide for Deloitte’s Insights Magazine or the WHO Data Design Language. Gabriele also wrote about adding touches of ethical guidance in guidelines in one of her recent newsletters. Enjoy!

We have Vidya Setlur on the show to talk about the role language, and natural language processing (NLP) play in data visualization and analytics.
Vidya is the director of research at Tableau and has a background in natural language processing and visualization. She is one of the main drivers behind Eviza, a research-based prototype and the corresponding product Ask Data, developed within Tableau to interact with data visualizations through natural language.
She is also the co-author, with Bridget Cogley, of Functional Aesthetics for Data Visualization, a new book on data visualization with a lot of information about semantics and language in data visualization.
In the episode, we talk about the challenges of going from a research prototype to an actual product, research vs. engineering, speech and natural language interfaces, the many ways language plays a role in visualization, the advent of language models, and much more.
Enjoy the show!

In this new episode, we talk about the interplay between statistics and data visualization. We do that with Andrew Gelman, Professor of Statistics and Political Science at Columbia University, and Jessica Hullman, Professor of Computer Science at Northwestern University. Andrew started the popular blog “Statistical Modeling, Causal Inference, and Social Science,” which has an active community of readers and has been around for many years. Jessica started contributing lately with many exciting posts, several of which have to do with data visualization. In the episode, we touch upon many topics, including the story behind the blog, the role of surprises, anomalies, and storytelling in science, the Anscombe’s quartet, and exploratory data analysis.

Hey all, we are back!
In this episode, we have Amanda Makulec to catch up on what happened during this whole period of time.
Amanda is a public health and data visualization expert and she is the Executive Director of the Data Visualization Society.
In the episode, we talk about the Data Visualization Society, the new Information is Beautiful Awards (now organized by the DVS team), and how visualization has evolved lately.
