Introduction

This introduction presents an overview of the key concepts discussed in the subsequent chapters of the book. This book introduces data visualization to communicators, from journalists and writers to professors, teachers, scientists and public relations professionals; or anyone interested in communicating data to an audience in a clear and visually appealing way. Large technology companies and industry researchers often refer to the “Three Vs” to define big data-for example, Gartner says: “Big data is high-volume, high-velocity, and/or high-variety information assets that demand cost-effective, innovative forms of information processing that enable enhanced insight, decision making, and process automation.” Although the book targets anyone who might want to visualize data to tell a story, most visualizations are appropriate for communications students. However, a data-driven story told via strong narrative and effective data visualizations can improve communications between colleagues or for audiences in any field.
