Line width.
Offset from the segment start coordinate. Usually equal to the size of the point object from which the segment starts to avoid overlapping with it.
Offset from the segment end coordinate. Usually equal to the size of the point object from which the segment ends to avoid overlapping with it.
Offset from the segment start coordinate. Usually equal to the stroke of the point object from which the segment starts to avoid overlapping with it.
Offset from the segment end coordinate. Usually equal to the stroke of the point object from which the segment ends to avoid overlapping with it.
Grouping key. If not set, grouping may be inferred from other aesthetics (e.g., color, size).
Auxiliary paint channel A that can be used as either color or fill as needed. Map a variable here for composite/multi-channel color with a matching scale.
