Infographic Design Case Studies & Practical Application 5 — Questions and Answers
Question 1: A food brand's infographic about sugar content goes viral but generates backlash because it compares grams of sugar in soda to grams in fruit using identical visual treatment. The core mistake is:
- Presenting nutritionally different contexts (added vs. natural sugar) as equivalent without that distinction (Correct answer)
- Using a bar chart instead of a pictograph
- Including too many product logos
- Failing to sort bars from highest to lowest
Correct answer: Presenting nutritionally different contexts (added vs. natural sugar) as equivalent without that distinction
Treating added and natural sugars identically omits a nutritionally significant distinction that changes the meaning of the comparison.
Question 2: A consulting firm's infographic on digital transformation uses a Sankey diagram showing resource flows. Most clients say they don't understand it. The best remediation is:
- Add an annotated callout explaining what the width of each flow represents before the reader encounters the diagram (Correct answer)
- Replace the Sankey diagram with a simple bullet list
- Use brighter colors for the flow lines
- Increase the diagram size to fill the full page
Correct answer: Add an annotated callout explaining what the width of each flow represents before the reader encounters the diagram
Unfamiliar chart types require a brief explanation of the encoding before readers engage with the data, reducing cognitive load.
Question 3: A health app wants to display daily step counts for a single user over 365 days. Which visualization approach handles the scale of data most effectively?
- A calendar heat map encoding step counts by color intensity for each day (Correct answer)
- 365 individual bar chart bars in a single horizontal chart
- A pie chart with 12 monthly slices
- A single number showing the annual total
Correct answer: A calendar heat map encoding step counts by color intensity for each day
A calendar heat map provides spatial familiarity (weeks and months) while encoding values through color, making patterns across an entire year scannable.
Question 4: A social media manager notices the brand's infographic gets shared mostly by cropping only the top third. What design adjustment would best address this?
- Place the most compelling statistic or visual hook in the top third of the design (Correct answer)
- Make the entire infographic shorter so it fits in one screen
- Add a watermark at the bottom to discourage cropping
- Increase the resolution so cropped versions are still high quality
Correct answer: Place the most compelling statistic or visual hook in the top third of the design
Since users share what they see first, putting the strongest element at the top ensures the cropped version still delivers the core message.
Question 5: A city government publishes an infographic about air quality improvement over 10 years. An advocacy group notes that the improvement period coincides with two major factory closures. Ethical data presentation requires:
- Acknowledging the factory closures as a contributing factor within the infographic (Correct answer)
- Removing the time period that overlaps with the closures
- Publishing a separate infographic about the factory closures
- Adding a footnote only visible in the downloadable version
Correct answer: Acknowledging the factory closures as a contributing factor within the infographic
Disclosing major external events that could explain a trend is essential for honest data communication and audience trust.
Question 6: A UX team A/B tests two versions of an infographic: Version A uses icons only, Version B uses icons with text labels. Version B has 34% higher task completion. The team should:
- Adopt Version B with text labels and document the finding to inform future projects (Correct answer)
- Ignore the result because icons are considered best practice
- Retest with a larger sample before making any design changes
- Compromise by using icons with labels only on mobile
Correct answer: Adopt Version B with text labels and document the finding to inform future projects
Empirical A/B data that shows a 34% improvement is actionable and should override design convention; documenting the finding builds organizational knowledge.
Question 7: A printed infographic poster for a conference must be readable from 6 feet away. The minimum recommended body text size for this use case is closest to:
- 24–36 points (Correct answer)
- 8–10 points
- 12–14 points
- 72–96 points
Correct answer: 24–36 points
Large-format print viewed at a distance requires significantly larger type than screen or document standards; 24–36pt body text is the practical minimum for 6-foot legibility.
