"A bar chart has an unlabeled horizontal axis and a vertical scale from 0 to 20. Bars for multiple unlabeled categories range from about 2 to 20. Most values fall between 5 and 17, with peaks near 19 and 20 and several lows around 2 to 4. Values fluctuate without a consistent upward or downward trend."
