Oval Layout

Arrange nodes evenly spaced around an ellipse. This creates an oval-shaped network layout that is wider than it is tall (or vice versa depending on ratio).

Usage

layout_oval(
  network,
  ratio = 1.5,
  order = NULL,
  start_angle = pi/2,
  clockwise = TRUE,
  rotation = 0,
  ...
)

Arguments

network

A CographNetwork or cograph_network object.

ratio

Aspect ratio (width/height). Values > 1 create horizontal ovals, values < 1 create vertical ovals. Default 1.5.

order

Optional vector specifying node order, as node indices or as node labels. Labels are matched for both CographNetwork and cograph_network input.

start_angle

Starting angle in radians (default: pi/2 for top).

clockwise

Logical. Arrange nodes clockwise? Default TRUE.

rotation

Rotation angle in radians to tilt the entire oval. Default 0.

...

Additional arguments (ignored).

Value

Data frame with x, y coordinates.
