Answer 1

A scatter plot is a two-dimensional data visualization that uses dots to represent the values obtained for two different variables - one plotted along the x-axis and the other plotted along the y-axis. For example this scatter plot shows the height and weight of a fictitious set of children.



Each dot represents one child with his or her height measured along the x-axis and weight measured along the y-axis.
