big trade

good morning I noticed that the big trade function is very useful but following the indications on the size of the circles I noticed that using the sizes (5,10, 20) you could lose them graphically if I do not enlarge the graph but I want to see a wider view , perhaps an idea, if these circles were better identifiable or could also use a larger size of 20 hypotheses up to 30 or 40 I could better identify certain important trades thanks
