I have sense say that there are something that never able to plot into graph.
d(A,B) = distance between A and B
For example, there are three point A,B and C. d(A,B) = 1000, d(C,A) = 1, d(C,B) = 1
My answer is Yes, We can.
By using the most mysterious thing in the universe, Time.
But the optimal time complexity will be O(N2) where N is number of neurons.
That is a reason why you never know how brain run because brain process hidden thing in O(N) but process thing to show to you in O(N2).
I am only an undergraduate student, so sorry if I am wrong.
