Circular layout

Places all nodes on a unit circle, optionally sorted by connectivity.

Usage

layout_circle(plot, order_by = c("id", "degree"))

Arguments

plot

A plotit object holding graph data, or a bare plotit_graph.

order_by

"id" keeps node-table order; "degree" sorts nodes by descending degree before placement.

Value

A modified plotit object (pipeline form), or a new plotit_graph when called on raw graph data.

Examples

e <- data.frame(source = c("a", "a", "b"), target = c("b", "c", "c"))
g <- as_graph(e) |> layout_circle()
g$nodes
#>   id          x    y
#> 1  a  0.0000000  1.0
#> 2  b  0.8660254 -0.5
#> 3  c -0.8660254 -0.5
