Data Storytelling with Scholarly Commons

What is Data Storytelling? 

Oftentimes data is presented in a manner that is dry or incomprehensible to a general audience. Data storytelling is a more interactive and compelling way to present information. Data storytelling is defined as using visualizations to tell a narrative that communicates insights about data to a wider audience.

When writing a data story, start by collecting your data. Look for the most interesting trends and determine the main points you want to get across in your data story. A data story should have a complete narrative rather than being a series of barely connected data visualizations. Make sure the story you are telling is appropriate for your audience.  

Resources for Creating a Data Story: 

The Scholarly Commons Collection is located in the UIUC Main Stacks. Books in this collection are available to check out. The collection includes books that provide introductory information to data storytelling. 

  1. Effective data storytelling : how to drive change with data, narrative and visuals 

This resource is available to UIUC faculty, staff, and students online. It focuses especially on the narrative aspects of data storytelling rather than the visualization aspect. This book explains the psychology of why storytelling is such an effective communication tool.  

  1. Storytelling with data : a data visualization guide for business professionals 

This resource is only available as a physical book. Data storytelling is a method often used by business professionals to impart information in a more meaningful and persuasive way. This book speaks specifically to business professionals and explains how to consider context, determine the appropriate format for the story, and speak to an audience in a compelling way.  

  1. Storytelling with data : let’s practice! 

This book is also available online with an active illinois.edu email address. It provides over 100 hands-on exercises to help you to gain practice in choosing effective visuals, keeping your visualizations clean, and telling a story.  

Scholarly Commons also provides access to various software that can be accessed on the computers in Main Library room 220. These tools can also be accessed through UIUC Anyware. Useful software for data storytelling includes: 

  1. Tableau Public

Tableau is a popular data visualization tool with many features useful for making many types of visualizations, such as histograms, pie charts, and boxplots. Tableau also allows users to create dashboards which create a comprehensive story by combining visuals and data.

If you have data you need to share with an audience, consider sharing it through a data story. Data stories are often more visually appealing and engaging than other methods of sharing data. The Scholarly Commons has lots of useful tools to help you create a data story! 

You can’t analyze data if you ain’t cute: Data Visualization

Meme from Reno 911 with the original text stating "You can't fight crime if you ain't cute" but the "fight crime" is crossed out and above is written "analyze Data"

Humans are highly visual creatures, even more so in our hyper-graphic world of ultra-filtered images and short aesthetic videos. Great ideas are ignored into oblivion in favor of shiny graphics and slick illustrations, so even data analysts need to be aware of how they present their findings. A well-designed infographic will be much more impactful, widely shared, and remembered than columns and rows of numbers. Even a simple graph can help people better come to conclusions and absorb information than they ever would with just numbers alone. People who can not only crunch numbers but also create stunning communications about those numbers are a real asset on the job market, so it behooves any hopeful data analyst to at least learn the basics of visualization.

*hacker voice* “I’m in” – Coding and Software for Data Analysis

While data analysis has existed in one form or another for centuries, its modern concept is highly tied to a digital environment, which means that people who are looking to move into the data science field will undoubtedly need some technology skills. In the data field, the primary coding languages include Python, R, and SQL. Software is a bit more complicated, with numerous different programs and services used depending on the situation, including Power BI, Spark, SAS, Excel, to name a few. While this is overwhelming, remember that it is not important to become an expert in all of the languages and software. Becoming skilled in one language and a few of the software options, depending on your interest or on the in-demand skills on job listings, will give you the transferable skills to quickly pick up the other languages and software as needed. If this still seems to be  an overwhelming prospect, remember that the best way to eat an elephant is one bite at a time. Take your time, break up the task, and focus on one step at a time!
