Abstract
Data visualization has grown in significance and complexity as the quantity of data and the technology supporting it have developed. Understanding and using data visualization is now a core skill that should be incorporated into information literacy goals by librarians and educators. Competency in data visualization is also closely related to data literacy and other quantitative literacies. Undergraduate students and other general learners should be exposed to the fundamentals of data visualization early in their education. This article proposes that evaluation, critique, and use of data visualization be the initial focus of education, and discusses some starting points for training in these three areas.
