Plot visualisation enables the distribution of multiple data sets across a two-
dimensional or even three-dimensional space to illustrate the relationship
between these data sets.
i. Scatter Plot
A scatter plot is a two-dimensional representation of the relationship
between two data points. Each symbol, including plus symbols, dots,
and squares, represents an observation. The value of each observation
indicates the position of the marker. The purpose of scatter plots is to
determine the relationship or correlation between X and Y variables.
