Infographic Design Infographic Design Data Visualization & Storytelling 1 — Questions and Answers
Question 1: Which chart type is BEST suited for showing how a whole is divided into parts?
- Line chart
- Scatter plot
- Pie chart (Correct answer)
- Bar chart
Correct answer: Pie chart
Pie charts visually represent part-to-whole relationships, making proportions of a total immediately clear.
Question 2: Edward Tufte's concept of 'data-ink ratio' advocates for:
- Using more decorative elements to engage viewers
- Maximizing the proportion of ink used to represent actual data (Correct answer)
- Balancing data visuals with equal amounts of text
- Adding gridlines for precision
Correct answer: Maximizing the proportion of ink used to represent actual data
Tufte's data-ink ratio principle states that as much ink as possible should represent data, eliminating decorative or redundant elements.
Question 3: What is 'chartjunk' in data visualization?
- Corrupt chart files that fail to render
- Unnecessary visual clutter that obscures the data (Correct answer)
- Overflow data that doesn't fit in the chart area
- Outdated chart styles no longer used in design
Correct answer: Unnecessary visual clutter that obscures the data
Chartjunk refers to unnecessary decorative elements—like excessive gridlines, 3D effects, or clip art—that distract from the data.
Question 4: A line chart is most appropriate when visualizing:
- Market share percentages
- Survey category rankings
- Trends over time (Correct answer)
- Geographic distribution
Correct answer: Trends over time
Line charts excel at showing continuous change over time, making trends, growth, and decline immediately visible.
Question 5: In data storytelling, what is a 'narrative arc'?
- A curved design element linking data points
- A structured progression from context through insight to conclusion (Correct answer)
- A branching decision tree within an infographic
- The curved axis of a radial chart
Correct answer: A structured progression from context through insight to conclusion
A narrative arc structures data presentation as a story: establishing context, building to a key insight, and ending with a conclusion or call to action.
Question 6: Which visualization type is best for showing the correlation between two continuous variables?
- Pie chart
- Bar chart
- Scatter plot (Correct answer)
- Stacked area chart
Correct answer: Scatter plot
Scatter plots plot individual data points on an X-Y axis, making correlation patterns, clusters, and outliers immediately visible.
