layout_oval: Oval Layout

In cograph: Analysis and Visualization of Complex Networks

Oval Layout

Description

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 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 (indices or labels).
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.

Examples

adj <- matrix(c(0, 1, 1, 1, 0, 1, 1, 1, 0), nrow = 3)
net <- CographNetwork$new(adj)
coords <- layout_oval(net, ratio = 1.5)
