so basically it's a completely random graph that has an equal chance of going up or down (100,000 times each graph), and it will collect averages on the graphs and it should be close to 0. You can also leave it running for extended periods of time just for kicks. *It will save the averages if you hit the stop button, so feel free to stop it while doing other things if it's slow.
I made this in an hour because I was bored. Don't judge me.
