121  |  Declarative Visualization with Vega-Lite and Altair with Dominik Moritz, Jacob Vanderplas, Kanit “Ham” Wongsuphasawat

[Data Stories runs thanks to the help of our listeners. Please consider supporting us on Patreon or sending us a one-time donation through Paypal. And thanks so much for your support!]

We have Dominik Moritz, Jacob Vanderplas, and Kanit “Ham” Wongsuphasawat on the show to talk about Vega-Lite and Altair. Dominik and Ham are PhD students at the Interactive Data Lab at the University of Washington with Jeff Heer, and Jacob is the director of Open Software at the University of Washington’s eScience Institute and the main person behind the development of Altair, the porting of Vega-Lite to Python.

Vega-Lite is a new declarative language for the development of interactive data visualizations based on a grammar of graphics (similar to R’s ggplot2). One of the most interesting innovations it provides is the development of a grammar that also includes interaction and linking between views. In addition, Altair brings Vega-Lite to the Python environment, making it available to innumerable data scientists who work in Python and the Jupyter Notebook.

On the show we talk about these two new environments, the grammar used by Vega-Lite, how to get started with it, and more.

Enjoy the show!

120  |  Data Science and Visualization with David Robinson

[Data Stories runs thanks to the help of our listeners. Please consider supporting us on Patreon or sending us a one-time donation through Paypal. And thanks so much for your support!]

This week we have David Robinson on the show to talk about data science, in particular the role of data visualization in data science. David is Chief Scientist at Data Camp and author of multiple data science books and R packages. He also writes a great blog called “Variance Explained.”

On the show we talk about visualization as a data analysis tool, the problem of validation in exploratory data analysis, and David’s opinion on programming versus GUI interfaces. Also, don’t miss his great advice — and very generous offer! — on how to get started in data science!

104  |  Visualization Literacy in Elementary School with Basak Alper and Nathalie Riche

[If you enjoy our show, consider supporting us on Patreon! You pay the amount of one or two lattes for each episode we publish every two weeks.]

In our latest episode, we talk about “C’est La Vis,” a research project developed to teach visualization at the elementary school level. 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.

103  |  Explorable Explanations with Nicky Case

[If you enjoy our show, please consider supporting us on Patreon! For the price of one or two lattes per episode, which we publish every two weeks, you can help make sure that Data Stories keeps getting made!]

This week we have Nicky Case on the show to talk about “explorable explanations,” interactive simulations that help people understand complex ideas.

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.

Enjoy the show!

091  |  Visualizing Data with RAW

[Help us become a crowdfunded podcast! Go to our Patreon homepage to become a Data Stories patron. Pledging starts at $3 per episode. And thanks!]

In this episode we have on a nice trio of Italian visualizers — Michele Mauri (Density Design), Giorgio Uboldi (Calibro), and Giorgio Caviglia (Trifacta) — to talk about RAW, the data visualization tool they built to help people visualize data interactively.

 

 

 

 

RAW is a very nice web-based and open-source data visualization tool that permits users to easily create charts without coding and to export them as vector graphics for further editing in external tools.

On the show we talk about why the team decided to develop RAW, how they got started, how they evolved RAW over time, the lessons they’ve learned, and their future plans.
