A histogram is a way of representing data in graphical form, letting us see how the data are distributed. Here is an example of a histogram:

Reading a histogram is easy. The height of each bin (the green rectangles) tells you how many elements with values corresponding to bin values are in the dataset.

In this histogram, we can see that there are exactly 3 elements with values from 0 to 10 (excluding 10) and 4 elements with values between 10 and 20 (excluding 20).
