Categorical data, also known as qualitative data, are bits of information that allow us to categories the things under inquiry into different groups. 

When working with categorical data, we normally start by summarizing the information into a frequency table.

A bar graph is a graph in which each category is represented by a bar, with the length of each bar representing the frequency of that category.

A vertical axis and a horizontal axis are required to create a bar graph.

 In this case, the vertical axis will have a scale and will measure the frequency of each category; the horizontal axis will not have a scale.

A pie chart is circular with wedges carved out in various sizes, similar to pie or pizza slices.

 The wedges' respective sizes correlate to the categories' relative frequencies.

What if he or she instead needs to compare the user bases' sizes, as well as the age groupings within each group?

 

A mosaic chart would allow the marketer to clearly and concisely explain all of the factors.

When comparing huge numbers of data points without respect to time, a scatter chart is the ideal option.

 This is a highly useful chart to use when you want to demonstrate the link between two variables (the x and y axes), such as a person's weight and height.

 Also, A scatter plot or scatter gram chart can highlight the distribution patterns or demonstrate the link between two variables. 

It should be utilized when there are a lot of distinct data points and you want to draw attention to the data set's commonalities. 

This is important when looking for outliers or trying to figure out how your data is distributed.
