Example 3
easyList three features that every well-made graph should have, and explain why each is important.
Solution
- 1 Feature 1: Clear axis labels with units — without labels, readers cannot interpret what is being measured (e.g., 'Sales (millions of dollars)')
- 2 Feature 2: Meaningful title — tells the viewer what the graph shows without requiring guessing
- 3 Feature 3: Appropriate scale starting at 0 (for bar/area charts) — starting above 0 exaggerates differences; scale should match data range
Answer
Good graphs need: labeled axes with units, a clear title, and an appropriate scale.
Data visualization is communication. Missing labels, misleading scales, and unclear titles all create misinterpretation. Every graph element should reduce ambiguity, not add it. Good design makes the data's story immediately clear.
About Data Visualization
