Creating graphs to do modulo calculation using graphviz and python

What you must have:

• python3
• graphviz
• Modify the external commands to suit your OS (default is Linux)

How to use the program:

• Modify the NUM constant to change the base
• Run the main.py using python3
• View the "mod_.pdf" file

How to use the graph: suppose you want to find (x mod 11):

• Initially, put your finger at vertex labeled "0"
• For each digit d in x:
  • Trace along one yellow arrow
  • Trace along d blue arrows
  • The label of the final vertex your finger is on is the answer.
