                 Scatterplot
                 The relationship between items depending on two separate variables and data sets can be shown using a scatter plot
                 or scatter chart. An x-y coordinate system is used to plot dots (or plot data). A trend line may be added to a scatter
                 plot in some instances.
                 For example:

                  Study Time (hours)   4    3.5   5    2     3   6.5   0.5  3.5   4.5   5    1    1.5   3   5.5   7
                      Percentage       82   82    90   74   40    94   51   75    86   85    62   75   70    89   95
































                 The most popular data visualization method in machine learning is the scatter plot.
                 When is a scatter plot suitable?
                    •  It is used to track the connections between two numerical variables. When the data are seen as a whole,
                   the dots on the plot indicate both the variable's value and any trends.
