Which example illustrates a crowded chart scenario?

• A. A line chart with 3 data points.
• B. The column chart showing the percentage of conversions for all 50 states may not have enough room to label each state clearly.
• C. A bar chart with 5 categories.
• D. A pie chart with 8 slices.

Answer: (B)

Crowded charts happen when there are so many categories or data points that labels and elements become cramped, making the chart hard to read. The column chart showing the percentage of conversions for all 50 states fits this perfectly because labeling each state would require many tiny labels and narrow bars, leading to overlap and illegibility. In practice, this reduces clarity and can mislead the viewer.

Other examples stay readable because they involve far fewer categories: a line chart with only three data points is simple to follow, a bar chart with five categories fits comfortably, and a pie chart with eight slices is still generally legible (though too many slices can become crowded, eight is usually manageable).
