Problemas de diagrama de acordes de red en R

Tengo algunos datos similares a los data.frame d como sigue.

d <- structure(list(ID = c("KP1009", "GP3040", "KP1757", "GP2243", 
                           "KP682", "KP1789", "KP1933", "KP1662", "KP1718", "GP3339", "GP4007",

               row.names = c(NA, -48L))

Quiero explorar las relaciones entre los miembros de d$ID usando un diagrama de acordes similar al de abajo.

Seesms hay varias opciones para hacerlo en R. (Diagrama de acordes en R ).

En mis datos las relaciones están de acuerdo con d$Set (no direccional) y la agrupación está de acuerdo con d$Loc. Los siguientes son mis intentos de mapear estas relaciones como un diagrama de acordes.

Intento 1: Usando igraph

He intentado igraph de la siguiente manera con el tamaño del nodo de acuerdo con el grado.

# Get vertex relationships
sets <- unique(d$Set[duplicated(d$Set)])
rel <-  vector("list", length(sets))
for (i in 1:length(sets)) {
  rel[[i]] <- as.data.frame(t(combn(subset(d, d$Set ==sets[i])$ID, 2)))
}
library(data.table)
rel <- rbindlist(rel)

# Get the graph
g <- graph.data.frame(rel, directed=F, vertices=d)
clr <- as.factor(V(g)$Loc)
levels(clr) <- c("salmon", "wheat", "lightskyblue")
V(g)$color <- as.character(clr)

# Plot
plot(g, layout = layout.circle, vertex.size=degree(g)*5, vertex.label=NA)

introduzca la descripción de la imagen aquí

¿Cómo modificar la trama para que se parezca a la primera figura? Parece que no hay opciones para modificar igraph layout.circle.

Intento 2: Usando Circlize

Parece que las curvas bezier más suaves y la agrupación son posibles en el paquete R circlize. Pero aquí no soy capaz de agrupar los nodos, así como ajustar su tamaño según el grado, ya que se representan como sectores.

par(mar = c(1, 1, 1, 1), lwd = 0.1, cex = 0.7)
circos.initialize(factors = as.factor(d$ID), xlim = c(0, 10))
circos.trackPlotRegion(factors = as.factor(d$ID), ylim = c(0, 0.5), bg.col = V(g)$color,
                       bg.border = NA, track.height = 0.05)
for(i in 1:nrow(rel)) {
  circos.link(rel[i,1], 0, rel[i,2],0, h = 0.4)

}

introduzca la descripción de la imagen aquí

Aquí sin embargo no hay opciones para modificar los nodos. De hecho, solo se pueden trazar como sectores? En este caso, ¿hay alguna forma de modificar los sectores en nodos circulares de tamaño según el grado?

Intento 3: Usando edgebundleR(https://github.com/garthtarr/edgebundleR ) 

require(edgebundleR)
edgebundle(g,tension = 0.1,cutoff = 0.5, fontsize = 18,padding=40)

Odio agregar otra respuesta para un problema diferente, pero no conozco ninguna manera de manejar la pregunta adicional planteada en el comentario. El comentario preguntó cómo podríamos colorear los bordes. Generalmente, la respuesta sería fácil, pero en este caso, la respuesta requiere una reescritura de gran parte del código en edgebundleR o requiere un hackeo. Voy a ir con el hack de abajo.
