• Histogram charts: They are charts used to show the frequency of
an event. Thus, the following chart exhibits the frequency
distribution of services provided.

• Line charts: They are used to exhibit the trend of continuous data over
time [1]. The chart below shows an increase in real GDP across years
(1947 to 2018)

• Scatter plots: they are used to show the relationship between two
variables, which exhibits either a positive or negative
relationship. The following scatter plot show the relationship
between GDP and personal expenditure

• Box Plot: They are graphical representation of measures of dispersion,
which include median, interquartile range, 75- and 25-percentile value
in a data set. Moreover, the graphical representation exhibits any
outlier in the data. Therefore, the following data box plot shows the
median, 75- and 25-percentile value.

• Bubble Chart: Notably, in the event a decision maker seeks to show the
association between more than two variables its recommendable to use
the bubble chart o matrix scatter plot [1]. The following bubble chart
exhibits the relationship between GDP, personal expenditure, and goods
