8 Summary of Published Works to Date This chapter summarizes a review of the existing literature and guidance currently available about visualizing performance measures and the relevance of that material to the overall synthesis. Due to the current evolutionary nature of the topic, much of the most recent information is addressed in the literature primarily through websites, conference presentations, or other forms of presentations that address more retrospectively what is already being put into practice.

10 Visualization of Highway Performance Measures In this book, Roam asserts that data visualization assists with problem solving and suggests that "the heart of business is the art of problem solving." He goes on to ask, "What if there was a way to more quickly look at problems, more intuitively understand them, and more rapidly convey to others what we've discovered? " Roam then lays a foundation for making strategic choices in creating data visualizations by explaining that there are six ways we see, which relate to six ways we can then show what we see.

Literature Review 11 Storytelling with Data: A Data Visualization Guide for Business Professionals by Cole Nussbaumer Knaflic, published in 2015, speaks to the increasing trend toward visualization that is occurring in the marketplace at-large and toward the demand that exists for increasingly more informed guidance on the subject. This book is organized around the theories of audience, clarity of design, and visual storytelling, all essential principles initially introduced by Edward Tufte's seminal works.

14 Visualization of Highway Performance Measures The Harvard study also speaks to possibilities of why many of the initial principles identified by Tufte have endured in both theory and practice over the last several decades. These principles again include simplicity, clarity, working with expectations of an intended audience, and use of narrative strategy.

18 Visualization of Highway Performance Measures best meets the vision established by the concept selected in Step 2 and then determining the methods by which the visualization will be shared with the intended audience. While most of this particular information is included in the published report, the extended value of the project rests in the ongoing collection of resources by the published website.

20 Visualization of Highway Performance Measures The Vizguide publications assert the complexity of the need for determining a strategy in approaching the design of any data visualization. They posit that it is not just a matter of selecting the appropriate type of chart or graph, "but also how you customize your charts and illustrations to reflect your intent, your audience, and the elements of your data." They go on to suggest that the essential tasks when choosing a strategy include • Selecting a chart type or types, • Selecting a medium, • Differentiating your data points, and • Ensuring that your visualization is useful, clear, and memorable for your audience.
