問題文
A tile must compare the number of support tickets across 8 product categories for a single month. Which chart type is the most appropriate?
選択肢
- A line chart, because connecting the categories for the month and for the products shows how the counts relate to each other.
- A scatter plot, because the vertical position of each point encodes the count for its category and the horizontal axis separates them.
- A bar chart, because the length of each bar allows direct comparison of magnitudes across the categories.
- A scorecard per category and a product group for it, because each category then gets its own prominent figure.
