Questions about netVisual circle() drawing

[JosieCen]

When I use the following code to draw a communication graph, the pattern appears strange, is there something wrong?

groupSize <- as.numeric(table(cellchat@idents)) 
par(mfrow = c(1,2), xpd=TRUE) 
netVisual_circle(cellchat@net$count, vertex.weight = groupSize, weight.scale = T, label.edge= F, title.name = "Number of interactions") 
netVisual_circle(cellchat@net$weight, vertex.weight = groupSize, weight.scale = T, label.edge= F, title.name = "Interaction weights/strength")

After I modified the arrow.width and arrow.size parameters to the following code, I obtained a relatively normal image. Why are the default parameters set so large? It's strange. Was it my operational error that caused this problem regarding the arrows? And the arrows on the graph don't seem like arrows... How can I modify it to be normal?
