I am trying to make a diagram with multiple nodes, and I think it is going to be much cleaner to read if I use rounded square arrows between the nodes. I have drawn an example with most types of curving arrows I will need to use in the figure below:
I tried this using ".. controls (x,y) and (z,w).." but it becomes too rounded. It's actually ok this way, but I think it will be much better if it had rounded square arrows instead.
Can someone tell me how to do these, using the tikzpicture environment, of course.
Thanks in advance!
