Happy Tuesday. :)
Want to join a study group to solidify your Data Viz theory?
These three university courses are amazing:
If you become a Paid Subscribers (subscribe here), I invite you to a discord where we can work through the courses together.
We’ll setup chat rooms for each week of the course. This way you can work through it asynchronously and get your individual questions answered.

Alright - on to this week’s links I thought were worth sharing…
Data Visualization Articles & Videos
Introduction to Accessible Contrast and Color for Data Visualization
This notebook serves as a general introduction to the topic of contrast and color use in data visualization as well as a landing page for all the notebooks in this series…GIS 101: Mapping data points in R [YouTube]
In this beginner's tutorial, I take you on a journey from loading and cleaning up the Geonames database to slicing and dicing the data to create an effective and pretty bubble map in R!…Debunking the data-to-ink ratio [Twitter Thread]
Recent #dataviz research suggests that charts with visual associations for the reader are more memorable. For ex, a graphic with pictograms may be better recalled, as long as those pictograms are relevant to the data…Nitrogen Dioxide in the Neighborhood
Los Angeles is often shrouded by pollutants like nitrogen dioxide. Now researchers know exactly which cities, neighborhoods, and even which property types are most affected. My final @NASAEarth piece, reported by the fantastic @EnviroEm…
Word-As-Image for Semantic Typography
A word-as-image is a semantic typography technique where a word illustration presents a visualization of the meaning of the word, while also preserving its readability. We present a method to create word-as-image illustrations automatically….Causalvis: Visualizations for Causal Inference
Causal inference is a statistical paradigm for quantifying causal effects using observational data…In this paper, we address this gap with Causalvis, a Python visualization package for causal inference. Working closely with causal inference experts, we adopted an iterative design process to develop four interactive visualization modules to support causal inference analysis tasks…Data Hierarchy Best Practices to Elevate Your Data Visualizations
Information hierarchy determines how data is grouped and aggregated. In design, and especially in data visualization, all aspects of a dataset cannot be equally emphasized. In order for any element to stand out, others must fade into the background. Effective data visualization often begins with gaining an understanding of the proper hierarchy (or hierarchies) to surface in your visualization and giving your users an appropriate interface for navigating that hierarchy…The grammar of tables in python (pandas) and R (gt)
The {ggplot2} is one of the most widely used packages for data visualization in R. It is based on Grammar of Graphics, Wilkinson (2012), and allows you to generate plots using layers. On the other hand, the Grammar of Tables {gt} is used to generate tables with a structure similar to that of {ggplot2}, using layers. Both approaches can be combined with tables that include graphics. In this case, I put together an example with data provided by the open data portal of the Autonomous City of Buenos Aires. The example is replicated with {pandas}…
Performance is not enough: a story of the Rashomon's quartet
Following the Anscombe's quartet point, in this paper, we present a synthetic dataset for which four models from different classes have practically identical predictive performance. But, visualization of these models reveals that they describe this dataset in very different ways…We believe that this simple illustration will encourage data scientists to visualize predictive models in order to better understand them…The Data Book List from Schilling Data Studio
What books about data and data visualization should you read? Here's a list of books about data and data visualization, recommended by me and others in the Schilling Data Studio community…Map of all active & planned Solar System missions & their destinations as of March 1st 2023
Here's my map of all active and planned Solar System Missions and their destinations as of March 1st 2023..The next events will be a Lunar Flashlight Moon flyby to prepare for orbit insertion in May, Hakuto-R1's Moon orbit insertion in April, followed by landing on the Moon near Atlas Crater in May…Sunday Profile: Amanda Montañez, Graphics Editor at Scientific American
We were to catch up with Amanda Montañez, graphics editor at Scientific American, to hear about a new position within the Graphics Group at the magazine…Moving on... is moving back!
A little over 6 years ago, I wrote about quitting my job and becoming a data visualisation freelancer. Today, I write about quitting my freelance life, and becoming an employee again…
Have an awesome week!
