Histogram

A histogram, also known as a frequency distribution graph, represents various ranges of data and are plotted within an X and Y axis. This graph can abridge large amounts of data.
The example map is of the "average value of dwelling variable, but this time with marked class breaks. With this particular distribution, class breaks are defined based on the ±0.5, ±1.5 and outside of±1.5 standard deviations from the mean value." This information is per the website.
