All in Data Visualization

Preparing for the Tableau Desktop Specialist Certification Exam

You may be able to relate to my personal routine: Every day I check my Twitter feed and am blown away by the Tableau community’s ability to visualize data in the most unique and powerful ways. Many of the vizzes that go viral incorporate the latest in new features—from transparent worksheet backgrounds to the incredible power of dashboard set actions. These new features are not only exciting, but serve as a motivator for me to embrace those Tableau basics such Level of Detail Expressions and calculated fields. Mastering Tableau basics will hopefully help me build a solid foundation so that I can fully understand how to correctly use these new features. For instance, it is a little hard to understand set actions if you have never created a set.

Storytelling with Data

I was first introduced to Cole Nussbaumer Knaflic’s book, Storytelling with Data when I was a student in the University of Washington Data Visualization Certificate Program, where I currently serve in the role of a grader. Cole’s book had an instant appeal in offering such a practical approach to data visualization in contrast to the stuffy approach taken by other books on the topic. Storytelling with Data along with Alberto Cairo’s The Truthful Art: Data, Charts, and Maps for Communication and Edward Tufte’s, The Visual Display of Quantitative Information are my top three must-read books for anyone interested in learning the basics of data visualization.
