Internally,
we map any desired layout direction to the variant of creating a left-to-right drawing.
This is done by transforming the input graph's coordinates in various ways.
Depending on the way this transformation is performed,
one can either preserve a _reading direction_ or _rotation_.
When preserving reading direction,
the vertical reading direction of a left-to-right or right-to-left layout
(and thus the node, edge, and edge label order) corresponds to the horizontal reading direction
of a top-to-bottom or bottom-to-top layout.
When preserving rotation,
the four possible drawings are simply rotated versions of the left-to-right variant.
This might be of interest if one wants to preserve a _clockwise orientation_
of feedback loops.
The following drawings illustrate the different behaviors.
### Reading Direction
### Rotation
