Storytelling With Data

The book is a highly recommended read for anyone working in the data analysis field as it provides valuable insight into the importance of data visualization and provides practical lessons that can enable data-driven communication. I have summarized my key lessons from it within the following pointers:

1. Understand context: The key lesson is to understand context before diving into data visualization. It clearly defines the audience and their needs. By choosing who you are communicating with and what they might want to do, you can tailor your visualizations accordingly. Additionally, it’s important to know how best to engage with your audience and use the available data to support your story.

2. Choose the appropriate visual display: Choosing an appropriate visual display is another crucial aspect highlighted in the book. Different data types require different approaches to visualization. For example, plain text is effective at highlighting individual numbers, while graphics are appropriate for representing continuous information. Bar charts are recommended for categorical data, ensuring a zero baseline. It is recommended that you avoid using pies, donuts, 3D charts, and secondary y-axes as they can complicate interpretation.

3. Eliminate clutter/confusion: To enhance audience comprehension, the book emphasizes the importance of removing confusion from visualization. Everything added to a page or screen places a cognitive burden on the audience. Viewers are more comfortable interpreting images if they use a method of identifying and eliminating features that do not add information value. Use contrast, accuracy of objects, and white space to help make the interpretation of your visuals a comfortable experience for your audience.

4. Focus attention where you want it: Highlighting the elements you want in visualizations is important. The book suggests using pre-attentive attributes such as color, shape, and position to convey significance. The effectiveness of these attributes can be assessed by examining where the audience’s eyes are drawn.

5. Think Like a Designer: The book encourages professionals to think like artists and provides insights that will guide the audience’s interaction. This includes highlighting key information, eliminating distractions, creating a visual structure, font, and using text for presentation. Beautiful illustrations can increase the audience’s tolerance for design issues and contribute to their acceptance of graphic designs.

6. Tell a story: Finally, the power of storytelling is emphasized. Crafting a clear narrative, adding conflict and tension, and maintaining the audience’s attention throughout are key. Strategies such as repetition, plotting are recommended, use logical sequences, paradoxes, and new perspectives to ensure clear communication.

Almost anyone can create use tools to create charts and graphs. However, few people can use data to tell a story but by following these lessons, data professionals can better interact with data and improve their data analysis, visualization skills and generally, their communication with data.
