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)
library(ggraph)

g <- sample_gnp(10,0.4)
## Not run:

 geom_edge_link()+
 geom_node_point(shape=21,fill="grey25",size=5)+
 theme_graph()+
 coord_fixed()

## End(Not run)
