what does univariate and bivariate mean on a scatter?

In the context of scatter plots, "univariate" and "bivariate" refer to the number of variables being analyzed or plotted.

- Univariate scatter plot: A scatter plot showing the relationship between two variables, where each data point represents one observation. It displays the relationship between two univariate (single-variable) data sets.

- Bivariate scatter plot: A scatter plot showing the relationship between three variables. It displays the relationship between two bivariate (two-variable) data sets. In this case, the x and y axes represent two variables, and the size, color, or shape of the data points may represent a third variable.
