Visual Explanations: Images & Quantities, Evidence & Narrative

By Scott J. Pearson | January 19, 2025January 19, 2025 by Scott J. Pearson

“A picture is worth a thousand words,” so the saying goes. Thus, an effective visualization, enriched by information, must count for so much more. But a misconstrued visualization, unfortunately, can lead to horrific outcomes from misinterpretations. How can we refine our visual thinking so that we can infer correct deductions while ignoring misplaced sketches? Visualization guru Edward Tufte teaches us how to reason about our world through informative displays in this helpful guide, replete with…

Envisioning Information by Edward Tufte

By Scott J. Pearson | January 12, 2025January 12, 2025 by Scott J. Pearson

All the way back to Galileo sharing about Jupiter’s moons, science has relied upon visualizations to communicate its findings. Some things are just better depicted visually instead of through words. In contemporary society, information graphics have played an increasingly larger role as computers quickly translate data into a more accessible format. Newspapers and Internet websites have made them commonplace. Even though this book was written in 1990, before ubiquitous computing, it identifies the philosophical and…

Beautiful Evidence by Edward Tufte

By Scott J. Pearson | December 30, 2024December 30, 2024 by Scott J. Pearson

Edward Tufte’s books on data visualization are nothing short of legend among us information geeks. A political scientist by training, he demonstrates how well-conceived visualizations can effectively communicate insights and how shortcomings can create catastrophes. He continues his famous series on visual imagination with this book on the intersection of data and art. He shows how displays of evidence can move readers much like art and how poorly constructed displays can inhibit good judgment. Tufte’s…

Creating Software with Modern Diagramming Techniques: Build Better Software with Mermaid

By Scott J. Pearson | July 28, 2024July 28, 2024 by Scott J. Pearson

As a computer science major in college, I learned about Unified Modeling Language (UML) as a way to visually document software. However, I soon found designing and maintaining those images to be more of a pain than they’re worth. I had to reshuffle images on graphics programs for every minor change, so keeping documentation up to date proved to be impossible. Recently, however, I discovered that someone invented a language, called Mermaid, to convert a…

Now You See It: An Introduction to Visual Data Sensemaking

By Scott J. Pearson | April 28, 2024April 28, 2024 by Scott J. Pearson

We live in an era, the so-called Information Age, where data collection has become incredibly easy. The term “Big Data” gets thrown around casually as computers collect more information on us than we know how to process. Yet wise interpretation of those data is often elusive. We’re overwhelmed with it. Effective visualizations and charts can help us interpret it better, whether to present and persuade or to monitor and manage. Stephen Few, an eloquent minister-turned-data…
