what is a scatter plot graph
A scatter plot, scatterplot, or scattergraph is a type of mathematical diagram using Cartesian coordinates to display values for typically two variables for a set of data.If the points are color-coded you can increase the number of displayed variables to three.or a set of data variables (dimensions) X 1, X 2, ... , X k, the scatter plot matrix shows all the pairwise scatter plots of the variables on a single view with multiple scatterplots in a matrix format. For k variables, the scatterplot matrix will contain k rows and k columns.
