Description

annotate concentric circles

Usage

annotate_circle(cent, col = "#00BFFF", format = "", pos = "top", text_size = 3)

Arguments

cent	centrality scores used for layout
col	color of text
format	either empty string or 'scientific'
pos	position of text ('top' or 'bottom')
text_size	font size for annotations

Details

this function is best used with layout_with_centrality together with draw_circle.

Value

annotated concentric circles around origin

Examples

library(igraph)

g <- sample_gnp(10, 0.4)
## Not run: 
library(ggraph)
ggraph(g, layout = "centrality", centrality = closeness(g)) +
    draw_circle(use = "cent") +
    annotate_circle(closeness(g), pos = "bottom", format = "scientific") +
    geom_edge_link() +
    geom_node_point(shape = 21, fill = "grey25", size = 5) +
    theme_graph() +
    coord_fixed()
