How can I move labels outside of the circles utilizing R's DiagrammeR package? I don't see anything in the instruction manual. Here's my code. In my opinion it's not visually appealing to have the labels inside the circles. If I could apply ggrepel to DiagrammeR that would be ideal, although I doubt this is possible.
library(DiagrammeR)
grViz("
digraph neato {
graph [layout = neato]
node [shape = circle,
style = filled,
color = grey,
label = '']
node [fillcolor = red]
a [label='Amelia Arduino', fixedsize = true]
node [fillcolor = green]
b c d
node [fillcolor = orange]
l [label = 'Larry Lamp', fixedsize = true]
edge [color = grey]
a -> {b c d}
b -> {e f g h i j}
c -> {k l m n o [label = 'Ophelia Oz', fixedsize = true]
p [label = 'Peter Pete', fixedsize = true]}
d -> {q r s t u v}
}")
