Lakeside Library Books Borrowed — Pictograph

This pictograph shows books borrowed by four classes from Lakeside Library during one week. Each circle represents one book, so readers can count the marks as well as compare the height of the groups. The small scale keeps the visual direct and appropriate for an early data lesson. Maple borrowed eight books, Oak borrowed eleven, Pine borrowed six and Cedar borrowed nine. The chart is deliberately limited to a few categories and whole-number values. If the library needed to report hundreds of loans or many weeks at once, a standard column chart would make the comparison clearer and more compact.
