Hi Everyone! We have Jon Schwabish on the show in this episode. Jon is an economist who specializes in data visualization for politics and economics. You can see some of his work in the blog he writes called Policyviz.
We invited him to talk about his recent new initiative called HelpMeViz, a web site where people can send requests to visualize some data of interest or redesign some particularly tricky charts. The web site quickly gained some momentum and already publishes quite a nice set of charts, suggested redesigns, and most of all very insightful discussions (it’s not just the usual I like this, I like that). There is a lot to learn there.
In the interview we talk about how HelpMeViz was born, how it works, what kind of entries they have been published so far and how it’s going to evolve. Give a look to HelpMeViz and submit your own charts and data there!
And here’s another piece of great news: For the first time, this episode was audio edited and annotated by a volunteer helper – woo! Fabricio Tavares was kind to help us. Thanks a million! The equation is simple: less audio editing work for Moritz means more episodes we can do in a year. Get in touch in case you would like help us, too!
Research paper on the benefit of visual difficulties: “Hullman, Jessica, Eytan Adar, and Priti Shah. “Benefitting InfoVis with visual difficulties.” Visualization and Computer Graphics, IEEE Transactions on 17.12 (2011): 2213-2222.”
Here we go folks. Another year has passed. We review what was big and major trends in 2013 and what to expect in 2014.
We have two old DS friends on the show to help us with the review: Andy “Visualisingdata” Kirk and Robert “Eagereyes” Kosara.
Important announcement: in 2014 we want to hear more from you! Please feel free to contact us to ask questions, we will address them in our upcoming podcasts. You can also suggest new guests or topics you would like us to cover. You can reach us through: Twitter (@datastories) | Facebook | Email: firstname.lastname@example.org. We are looking forward to hearing from you!
We have Marian Dörk on the show today to talk about the “Information Flaneur”: an approach to data visualization centered on navigating, exploring, browsing and observing the data with curiosity to learn about what’s there to see and to be surprised by new thoughts and discoveries.
Marian is Research Professor at the University of Applied Sciences Potsdam near Berlin where he works on “exploring novel uses of interactive visualizations to support a wide range of information practices”.
We talk about many interesting new directions for visualization like the visualizing data starting from a few seed points, whether we always need an overview first in visualization and tips on how to design visualization for “information flaneurs”.
We have a super guest this time on the show! Ben Shneiderman joins us to talk about his new treemap art project (beautiful treemap prints you can hang on the wall), treemaps and their history, and information visualization in general. Needless to say, we had a wonderful time chatting with him: lots of history and very inspiring thoughts (tip: we should look at vis 50-100 years from now!)
We did it again: we have a special episode directly from IEEE VIS’13 (the premier academic conference on visualization). Enrico caught Robert Kosara and recorded almost one hour of highlights from the conference. And there is a final message for Moritz too! Don’t miss it.
Here we go with another great episode. This time more on the data side. We have Kate Crawford (Principal Researcher at Microsoft Research) on the show talking about the other face of big data. That is, after all the excitement, hype, and buzz, she is the one who is asking the tough questions: Is more data always better? Is there any objective truth in it? Is big data really making us smarter? Etc.
We are back after a relaxing summer with a brand new episode! We have Petra Isenberg, from the Aviz team at INRIA (we had other guests from the same lab in the past) as guest talking about visualization on non-standard devices and environments. Yes, stuff like display walls, surfaces, tabletops, and people collaborating around them. It feels like the future is here and there’s a ton of potentially interesting applications for visualization.
Petra gives us hints on what works what does not work, what research says, what has been tried already and what needs to be explored, etc. She also gives practical recommendations at the end on how to start doing visualization on these devices. That’s really cool stuff!
In this episode we talk about visualization on mobile and touch devices. How do you design visualization interfaces for this kind of devices? How different is it to interact with your fingertips rather than with your mouse? Advantages, disadvantages, unexplored opportunities?

In this episode we talk about the VAST Challenge, a visual analytics contest organized every year co-located with the IEEE VIS Conference, the premier venue for academic work in visualization.
The VAST Challenge has many unique features (like the generation of synthetic data sets with injected ground truth) and this year for the first time it features a predictive analytics and design mini-challenge (Stephen Few’s talked about it too here) you should definitely check out.
We talk with Prof. Georges Grinstein from UMass Lowell and Celste Paul from NSA. They give us lots of details about how the data is generated, how the entries are evaluated and how it looks like participating to the contest.
You guys should actually give it a try and rock it!
