Practical Examples

1. Choosing the right graph for your message

   Knaflic illustrates how the choice of graph can either clarify or obscure your message. For instance, she demonstrates why a line graph is better for showing trends over time compared to a pie chart. This stresses the importance of aligning your visual representation with the story you want to tell.

2. Removing clutter from data visuals

   The book offers practical advice on decluttering dashboards and charts. Knaflic shows before-and-after examples where excessive gridlines, labels, and colors distract from the key message, and then simplifies the visuals to draw attention exactly where it’s needed.

3. Using color for emphasis

   Knaflic explains how strategic use of color helps highlight important data points without overwhelming the viewer. She provides examples of using a single bold color to draw focus on a specific bar in a bar chart, making the story behind the data memorable and easy to grasp.

4. Annotated storytelling within visuals

   The book walks through techniques for building narrative with explanatory text directly on or near the visual. By annotating a chart with key takeaways, the reader is guided through the intended interpretation, reducing cognitive load and increasing understanding.

5. Iterative improvement process

   Knaflic emphasizes the importance of refining visuals through iterations. She provides case studies where an initial draft chart is improved step-by-step, based on feedback and self-review, culminating in a chart that communicates the message more powerfully.

6. Focusing audience attention

   She discusses deploying techniques such as pre-attentive attributes (size, color, position) to guide the viewer's eyes toward the most critical part of the data. This method is supported by examples showing how subtle visual cues can direct interpretation.

7. Structuring a data story

   Knaflic advocates for using a clear introduction, supporting evidence, and a strong conclusion when telling stories with data. This example shows how data, like any narrative, should be organized for logical flow and impact.

8. Eliminating chartjunk

   The book references historical advocacy (e.g., Edward Tufte) to show the dangers of 'chartjunk' like 3D effects and decorative imagery. She presents practical instances of transforming busy, hard-to-read visuals into sleek, communicative charts.
