Scatter Points

Description

<br /> The point geom is used to create scatterplots. The scatterplot is most <br /> useful for displaying the relationship between two continuous variables. <br /> It can be used to compare one continuous and one categorical variable, <br /> or two categorical variables, but a variation like geom_jitter(), <br /> geom_count(), or geom_bin2d() is usually more appropriate. A bubblechart <br /> is a scatterplot with a third variable mapped to the size of points.
