The correct answer is: D. all of the mentioned.
A lattice plot is a type of statistical graphics that is used to visualize the relationship between two or more variables. It is a type of overlayed 1D plot, which means that it is a plot that shows multiple lines on the same axes. The lines can represent different variables, or they can represent different groups of data.
A barplot is a type of statistical graphics that is used to compare the values of different variables. It is a type of overlayed 1D plot, which means that it is a plot that shows multiple bars on the same axes. The bars can represent different variables, or they can represent different groups of data.
A gplot is a type of statistical graphics that is used to visualize the relationship between two or more variables. It is a type of overlayed 1D plot, which means that it is a plot that shows multiple lines on the same axes. The lines can represent different variables, or they can represent different groups of data.
In conclusion, all of the mentioned options (lattice, barplot, and gplot) are also referred to as overlayed 1D plot.
