Arrange related variables in a set and visualize relations
I have a basic question, let me explain with this simple example;
b=var('b') c=var('c') d=var('d') e=var('e') f=var('f') g=var('g')
a = b + c m = d + e + b n = f + g + c
So everything is related to each other. I want to form some kind of set-system and visualize these relations in Sage with arrows and so on. How can I achieve this ?
