• The blocks are too close together.

Answer explanation

Explanation: The perspective distorts the data, making it harder to accurately compare block heights.

Qs04. What type of graphic is suggested as a better alternative for representing the data?

• A dot plot.
• A bar chart with gradients.
• A pie chart.
• A stacked area chart.

Answer explanation
