Why do you use a histogram?
Histogram is an illustrative way to represent a particular data. It is shown in vertical bar formation for a particular input and with respect to the number of continuous data given, which is said to be the frequency in each category.
A histogram is a single block graph of rectangles where the area of each rectangle will be proportional to the frequency.
