`mvar_object`	An object of class `mvarLayer` that we want to visualize.
`layers_list`	Either a list of lists containing detailed plotting layer options, or a character string matching one of a few defaults. If a list of lists is provided, we expect the i^th component to be a list whose names are any of "point", "text", and "arrow", and whose corresponding values are TRUE if that layer is to be added to the plot and FALSE otherwise. If a character is provided, we expect one of the following presets: points: We plot points for each layer. If no color aesthetic associated with row or column annotation is provided, each layer of points will be a different color. This is the default plot. text: This plots text for every layer. point-text: This plots points for the first layer and text for the second layer. Only applies to tables with two layers. text-point: This plots text for the first layer and points for the second. points-and-text: This shows both points and slightly offset points for every layer. point-text-arrow: This plots points for the first layer, and both text and arrows for the second layer.
`x`	The name of the column in the coord data to use as the x-axis in the desired plot. This will default to the first axis in the ordination.
`y`	The name of the column in the coord data to use as the y-axis in the desired plot. This will default to the second axis in the ordination.
`col`	The color to use for points or text in the plot. This can either be a column in one or more of the annotation objects, in which case the values from that annotation will be used for coloring, or a string specifying the actual color to use.
`fill`	The fill to use for points or text in the plot. This can either be a column in one or more of the annotation objects, in which case the values from that annotation will be used for filling, or a string specifying the actual fill color to use.
`shape`	The points to use for points in the plot. This can either be a column in one or more of the annotation objects, in which case the values from that annotation will be used for shape, or a string specifying the actual shape to use.
`size`	The size of points in the plot. This can either be a column in one or more of the annotation objects, in which case the values from that annotation will be used for size, or a string specifying the actual size to use.
`label`	The label to use for text in the plot. This can either be a column in one or more of the annotation objects, in which case the values from that annotation will be used for coloring, or a string specifying the actual color to use.
`...`	Other arguments passed on to layer. These are often aesthetics, used to set an aesthetic to a fixed value, like pch = 16. They may also be parameters to the paired geom/stat.
