Practical Examples

1. Choosing Proper Chart Types

   The book explains how to match data types and communication goals with appropriate chart types, such as line graphs for time-series data and bar charts for categorical comparisons. Few demonstrates pitfalls of misusing pie charts and 3D effects, emphasizing that these often distort perception rather than help it. He provides clear guidance on chart selection to maximize clarity.

2. Effective Table Design

   The book outlines best practices for designing tables, such as aligning numbers for ease of comparison, using white space for readability, and avoiding unnecessary lines. He provides before-and-after examples showing how subtle design tweaks lead to better data comprehension.

3. Labeling and Annotation Techniques

   Few emphasizes the importance of clear, direct labeling instead of relying on cryptic legends or color codes. He advocates for putting labels directly next to data points or lines, reducing the cognitive load required to interpret the visuals.

4. Handling Large Data Sets

   The book provides strategies for summarizing and highlighting patterns when faced with large tables or graphs. Few suggests spotlighting key rows, using callout boxes, or breaking down complex visuals into smaller, digestible parts to prevent overwhelming the audience.

5. Using Color with Purpose

   Few explains that color should be used sparingly and only to draw attention to critical data, not for decoration. He provides examples of how careful color choices can clarify trends or categories and how overuse can lead to confusion.

6. Telling a Clear Story

   He discusses structuring tables and graphs to guide the reader naturally from overview to detailed insights. Few shares examples of arranging columns and ordering bars to support the narrative flow and highlight the main message.
