67 | ggplot2, R, and data toolmaking with Hadley Wickham


We have Hadley Wickham on the show, Chief Scientist at RStudio and Adjunct Professor of Statistics at Rice University and the University of Auckland.

Hadley created a number of hugely popular libraries for the R language, including ggplot2, which is used throughout the world to analyze and present data.

On the show we talk about his creative process to develop ggplot2, its growing popularity, other libraries he has built in the R ecosystem, and strategies for creating popular software for data analysis and visualization.

Enjoy Hadley Wickham!

66 | “I Quant NY” Finding Surprising Stories in NYC Open Data with Ben Wellington


Happy New Year everyone, we are back!

In this episode we talk with Ben Wellington about his blog I Quant NY, where he writes about surprising facts he finds analyzing NYC open data.

Some of his stories include how he discovered that “… Software in Half of NYC Cabs Generates $5.2 Million a Year in Extra Tips,” ideas on “How to Fix NYC’s No-Cabs-At-4PM Problem” and “How NYC Open Data and Reddit Saved New Yorkers Over $55,000 a Year” by detecting fire hydrants that generate too many parking tickets.

On the show Ben talks about how he generates new ideas, how he finds and analyzes the data, and how he turns this into amazing stories for his blog. We also talk about the impact his work had on New York City and the interesting reactions some of his blog posts have generated.

Enjoy Ben and his amazing NYC data stories, and read a transcript of our interview here!

65 | What Happened in Vis in 2015? Year Review with Andy Kirk and Robert Kosara


Hey yo!

Another turn of the year is approaching and we take some time to reflect with our classic guests Andy Kirk and Robert Kosara on what has happened in 2015: “What where the major trends? Big debates? Best visualizations? New tools? Etc.

This was a great year for Data Stories, with a total of 22 episodes (our record so far!). We want to thank our fantastic collaborators Destry and Florian for their great support with running the show, our guests for spending time talking with us, and of course all of you for listening to Data Stories!

64 | “Dear Data” with Giorgia Lupi and Stefanie Posavec


Hey folks,

it’s time for another project centric episode, and we finally talk about one of our favorite projects of the year — “Dear Data”  by the most fabulous tag team of data illustrators around: Giorgia Lupi and Stefanie Posavec.



Their year-long project is about how “two women who switched continents get to know each other through the data they draw and send across the pond” and consists of 104 hand–drawn postcards all of which document one week of their lives. How much they cursed, laughed, read, smiled at strangers, … — all of this is documented in inventive, charming and very analogue ways.

Learn all about the project — how they started it, what they learned, and how it will live on — in the episode.

Here we go with a new project episode! This time we talk with Lisa Charlotte Rost about her project “My Google Search History“.

Lisa is a visualization designer based in Berlin and the project is about how she collected and visualized her google search history to look into her personal data.

In the episode we discussed how she came up with the idea and all the steps she followed to realize it.

She has also a nice page on github with code that you can reuse to do the same thing with your own data!

60 | Upcoming DS Events and Some of Our Recent Projects

Hey folks, we are back! We really hope you had a good summer.

We start the new season with an “internal” episode. We give numerous updates on Data Stories. Things we have changed recently, future ideas and two great events to get in touch with us!

  1. The Visualized conference, taking place in New York Oct 7-10, 2015, is going to host a Data Stories Meetup on Oct 7, 2015. If you live in NYC or happen to be around please drop by! We’d love to meet and talk with you.
  2. We will also give an Ask Me Anything on Reddit on November 3. This is a unique opportunity to ask us questions live and have a great chat together.

In the show we also talk about some of our recent projects.

Moritz talks about False Positive, an art project on data, privacy and identity. He also talks about the new Inclusive Growth Report from the World Economic Forum, for which he designed the graphics and website together with Stefanie Posavec and 9elements.

Enrico talks about the RevEx tool and his collaboration with ProPublica for the analysis of millions of medical Yelp reviews, his work with Human Rights experts and a recently published paper on visualization design with climate scientists.

59 | Behind the Scenes of “What’s Really Warming The World?” with the Bloomberg Team

Screen Shot 2015-08-20 at 1.17.38 PM

Different people, working for different institutions, in different countries, at different times, all come up with the same answer …

– Eric Roston, Bloomberg (talking about global warming)

Hi folks! We have Blacki Migliozzi and Eric Roston from Bloomberg on the show to talk about their recent data graphic piece on climate change called “What’s Really Warming The World?“.

The graphics shows, through a “scrollytelling”, what factors may influence the world’s temperature according to well established climate models and it guides your through a series of questions and visuals to see with your eyes what does correlate (spoiler: carbon emissions) and what does not.

On the show we talk about how the Bloomberg team came up with this piece, their interaction with the NASA Goddard Institute for Space Studies (GISS) scientists who developed the model, and the many challenges of translating important scientific knowledge into more digestible, but not simplistic, articles everyone can read.

We also talk about how for this graphic they took inspiration from the children book “Where’s Spot?” (which is a nice narrative technique for vis!) and all the delicate design decisions they had to make.

… And don’t miss the moment when Eric drops the huge IPCC (International Panel on Climate Change) report book to give a sense of how big it is!

Enjoy the show!

58 | Data Installations w/ Domestic Data Streamers


I believe we are bored from being 8 to 10 hours everyday in front of the screen, so when we go out from the screen the real life happens and things get more and more interesting

– Dani Llugany Pearson

Hey everyone, starting from this episode we will add images/photos of projects and ideas discussed on the show so that you no longer have to guess what we are talking about! Try this one below … if you click on it you’ll get high-res pictures. Let us know if you like it!

Hi folks,

We have Dani Llugany Pearson from Domestic Data Streamers to talk about the studio and their amazing participatory data installations.

You really need to see examples of what they do! Go to and take a look at their projects.

In Data Strings they ask people to add their own thread to a physical parallel coordinates. In Life Line they use a grid of 800 balloons to show the point between one’s real age and the age at which one would like to die. In Golden Age they use a grid to let people mark with a log what is their age and what they believe is the best age in people’s life.

On the show we talk about how they started and describe the process behind some of the projects.

Enjoy the show!
