Final answer:
Both histograms and bar charts are examples of graphs used to describe data, with histograms focusing on the distribution of continuous data and bar charts on comparing categorical data.

An example of graphs used to describe data includes both histograms and bar charts.

. On the other hand, bar charts display comparisons among categories using bars that can be oriented horizontally or vertically and represent a discrete value.
