We have economist Max Roser from University of Oxford to talk about his Our World in Data project where he visualizes the social, economic, and environmental history of humanity up to the present day.
Our World in Data is a remarkable project which Max started on his own little by little in the spare time and evolved into a full web site with plenty of interesting data, presentations and visualizations to to better understand humanity.
The nicest thing about it is that it provides a quite positive picture of the world and about in how many ways we are improving our conditions. Go to the website (http://ourworldindata.org/) and take a look at War and Violence, Poverty, Global Heath, Etc.
On the show we talk about how Max started and the process behind finding a topic, collecting and curating the data and producing these nice visuals people can easily understand. We also talk about human biases, persuasion, and how Max learned to build web sites and visualizations.
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!
Note: We suggest you give a look to the links below (under the heading “Cases We Discuss in the Podcast”) before listening to the podcast, most of the episode is centered around these examples we selected for discussion.

We talk about many practical and more philosophical aspects of publishing interactive visualization on the web. We also spend quite some time discussing about D3.js’s past, present and future.
(On a side note: apologies for starting a bit abruptly and for the weird noises. Enrico was desperately and unsuccessfully trying to find a quiet and calm spot at the CHI conference.)
Enrico & Mo.

We have two fantastic guests to talk about using visualization for the good. We actually decided to make it even bigger and provokingly titled it: can visualization save the world?
We have on stage: Kim Rees co-founder of Periscopic, a data visualization company guided by the motto: “do good with data” and Jake Porway, founder of Data Kind, an organization that brings together data scientists and social organizations.
