What type of chart represents a frequency distribution visually?

A histogram is specifically designed to represent a frequency distribution visually by illustrating the number of data points that fall within specified ranges or intervals (often referred to as "bins"). It allows viewers to quickly see patterns in the data, such as the shape of the distribution, central tendency, and variability. This type of chart is particularly useful for understanding the underlying frequency of continuous data, making it a fundamental tool in statistics.

In contrast, while line graphs show trends over time and pie charts depict proportions of a whole, they do not emphasize frequency distributions. Bar graphs can represent categorical data and may visually resemble histograms; however, they typically portray counts for distinct categories rather than continuous data intervals. Thus, a histogram is uniquely suited for this purpose.
