When selecting a chart type, what should you prioritize?

• A. Always use the same chart type
• B. Choose the chart that best fits the data and improves clarity by potentially adjusting data
• C. Use as many chart types as possible
• D. Only use 3D charts

Answer: (B)

Choose the chart type that best fits the data to communicate the message clearly. The best option is the one that matches the data’s structure and highlights the intended pattern, trend, or relationship, even if that means adjusting how the data is grouped or summarized to improve clarity. For example, use a line chart to show changes over time, a bar chart to compare categories, a stacked chart to show parts of a whole when there are only a few components, or a scatter plot to reveal a relationship between variables. Adjusting data grouping or aggregation can reveal the insight more effectively without distorting the story.

Avoid forcing the same chart type for every dataset, which can obscure differences or mislead. Also, skip 3D charts, as they often distort perception and make accurate interpretation harder. The emphasis should be on readability and accuracy.
