Overview
A picture is worth a thousand words, but developing a data picture worth a thousand words involves careful thought and planning. IT leaders are often in need of sharing their story and vision for the future with campus partners and campus leadership. Delivering this message in a compelling way takes a significant amount of thought and planning. This session will take participants through the process of constructing their story, how to (and how not to) incorporate data and anecdotes effectively, how to design clear data visualizations, and how to present their story with confidence.
Learning Objectives
During this course, participants will:
- Develop a story that elicits a specific outcome
- Identify and effectively use data elements to support a compelling story
- Learn how to tell your story in a clear and effective way
NOTE: Participants will be asked to complete assignments in between the course segments that support the learning objectives stated below and will receive feedback and constructive critique from course facilitators on how to improve and shape their work.

Upon completion of this course, you will be able to create basic data visualizations that are effective, accessible, and engaging. In support of that primary objective, you will:
- Describe the benefits of data visualization for your professional situation
- Identify opportunities for using data visualization
- Apply visual cues (pre-attentive attributes) appropriately
- Select correct charts/graphs for your data story
- Use appropriate accessibility strategies for data tables
Prerequisites
Basic knowledge of Microsoft Excel or Google Sheets is required to successfully complete this course. Resources will be included to help you with the basics should you need them, but time spent learning the tools is not included in the estimated time for completing this course.
What are the key takeaways from this course?
- The ability to explain how data visualization is connected to data analytics
- The ability to identify key data visualization theories

data storytelling

3 Reasons Why Data Storytelling Will Be A Top Marketing Trend of 2018
A study that looked at reader engagement across articles that contained charts and infographics vs. articles that were text-only found that those with graphical storytelling, or what I like to call data storytelling, had up to 34 percent more comments and shares and a 300 percent improvement on the depth of scroll down the page.
Using storytelling techniques to present data not only makes it more visually appealing but also enables easy spotting of key trends, seamless results-tracking, and quick goal-monitoring.
Here are things that can help you build a bridge from your current methods to effective data storytelling–
- Choose a topic by identifying your target audience, the goal of your visual, what you would like to achieve.
- Organize your data by thinking about what you want to convey and then get rid of anything that doesn’t help you tell that story.
- Spend time making your visualization look sharp by keeping it simple, using color and interactivity.
A few bonus tips to make your data visualizations really pop–
- Don’t use more than two graphs at a time so as not to confuse participants.
- Stick with one color per graph; making things multicolored will cause data to look jumbled.
- Give context to your concept. Introduce your idea slowly and tell the story of what you want your data to reveal instead of assuming everyone in the room is on the same page.
- Try using interactive data storytelling techniques to support your data.

academic library collection data visualization
Finch, J. f., & Flenner, A. (2016). Using Data Visualization to Examine an Academic Library Collection. College & Research Libraries, 77(6), 765-778.
p. 766
Visualizations of library data have been used to: • reveal relationships among subject areas for users. • illuminate circulation patterns. • suggest titles for weeding. • analyze citations and map scholarly communications
Each unit of data analyzed can be described as topical, asking “what.”6 • What is the number of courses offered in each major and minor? • What is expended in each subject area? • What is the size of the physical collection in each subject area? • What is student enrollment in each area? • What is the circulation in specific areas for one year?
libraries, if they are to survive, must rethink their collecting and service strategies in radical and possibly scary ways and to do so sooner rather than later. Anderson predicts that, in the next ten years, the “idea of collection” will be overhauled in favor of “dynamic access to a virtually unlimited flow of information products.” My note: in essence, the fight between Mark Vargas and the Acquisition/Cataloguing people
The library collection of today is changing, affected by many factors, such as demanddriven acquisitions, access, streaming media, interdisciplinary coursework, ordering enthusiasm, new areas of study, political pressures, vendor changes, and the individual faculty member following a focused line of research.
subject librarians may see opportunities in looking more closely at the relatively unexplored “intersection of circulation, interlibrary loan, and holdings.”
Using Visualizations to Address Library Problems
the difference between graphical representations of environments and knowledge visualization, which generates graphical representations of meaningful relationships among retrieved files or objects.
Exhaustive lists of data visualization tools include: • the DIRT Directory (http://dirtdirectory.org/categories/visualization) • Kathy Schrock’s educating through infographics (www.schrockguide.net/ infographics-as-an-assessment.html) • Dataviz list of online tools (www.improving-visualisation.org/case-studies/id=5)
Visualization tools explored for this study include Plotly, Microsoft Excel, Python programming language, and D3.js, a javascript library for creating documents based on data. Tableau Public©

p. 771 By looking at the data (my note – by visualizing the data), more questions are revealed, The visualizations provide greater comprehension than the two-dimensional “flatland” of the spreadsheets, in which valuable questions and insights are lost in the columns and rows of data.
By looking at data visualized in different combinations, library collection development teams can clearly compare important considerations in collection management: expenditures and purchases, circulation, student enrollment, and course hours. Library staff and administrators can make funding decisions or begin dialog based on data free from political pressure or from the influence of the squeakiest wheel in a department.

Prospect project
The Prospect project at UNC’s DIL
Prospect is a WordPress plugin. In an overly wordy sentence, Prospect is a domain-agnostic framework for data visualization in support of the digital humanities.
The concept is a simple one. We take data, and we represent it with images. We all get that part of it. The importance of that kind of work relies on the fact that we are humans, and we understand visual structures better and with more fidelity than we do tables of data.
Digital humanities isn’t just limited to the humanities – the design concepts that guide that field are relevant to all domains. At that level what we’re really talking about is a digital literacy, and one that will be instrumental in many of the possible futures that exist for our students.
