For example the linear statistical transformation plot from Section 7.3 can be customized both with the marker objects in the scatter plot but also with the line object in the linear trend plot. We can customize anything that the Makie.jl’s plotting types support inside visual:

Figure 62: AlgebraOfGraphics customized scatter plot with linear trend estimation.

• : a Symbol for a light blue color, :steelblue

Inside the linear statistical transformation we are adding a new layer to be fused into it with the operation, that does not have a positional argument for plotting type since linear already provides a default plotting type, and has the following keyword arguments:

• color: a Symbol for the red color, :red
• linewidth: a number representing the width of our line
