Layout as arc using the alter package.

layout_arc(
  g,
  sourceWeight = NULL,
  targetWeight = NULL,
  thickness = 0.05,
  marginRatio = 0.1
)

Arguments

g	An object of class `g2r` or `g2Proxy` as returned by `g2()` or `g2_proxy()`.
sourceWeight, targetWeight	Bare name of column containing weights of source and target in the edges data.frame.
thickness	Node height, between `0` and `1`.
marginRatio	Space ratio, between `0` and `1`.

Examples

ig <- igraph::erdos.renyi.game(100, 1 / 100)

g2(ig, asp(x, y)) %>%
  layout_arc() %>%
  fig_edge(asp(color = source, shape = "arc"), opacity = .3) %>%
  fig_point(asp(color = id, shape = "circle", size = value)) %>%
  coord_type("polar") %>%
  coord_reflect("y") %>%
  axis_hide()

g2(ig, asp(x, y)) %>%
  layout_arc() %>%
  fig_edge(asp(color = source, shape = "arc"), opacity = .3) %>%
  fig_point(asp(color = id, shape = "circle", size = value))
