SugiyamaOptions

SugiyamaOptions(
    margin=(30.0, 30.0),
    direction='RIGHT_UP',
    socket_alignment='NONE',
    add_reroutes=False,
    keep_reroutes_outside_frames=False,

Options for the Sugiyama (layered) arrangement.

Parameters

Name	Type	Description	Default
margin	tuple[float, float]	Horizontal and vertical space between nodes.	(30.0, 30.0)
direction	str	Which directions nodes may be moved in during layout.	'RIGHT_UP'
socket_alignment	str	How aggressively links are straightened by aligning the sockets they connect.	'NONE'
add_reroutes	bool	Insert reroute nodes to route long edges around nodes. Off by default: added reroutes are real nodes, which would change the authored structure of generated trees (node counts, round-trips, diagrams).	False
keep_reroutes_outside_frames	bool	Do not place added reroutes inside frames.	False
stack_collapsed	bool	Stack consecutive collapsed nodes tightly.	True
stack_margin_y_fac	float	Fraction of the vertical margin used between stacked collapsed nodes.	0.5
optimize_sizes	bool	Fit the widths of collapsed nodes to their display name.	False
iterations	int	Number of crossing-minimization iterations.	50
