checkpoint 3:
I am not sure If my final code ran correctly. I think it was supposed to be a scatter plot like the one you showed originally, but not sure. Everytime I ran the code after I was done, it changed the scale each time. Overall...before writing the function for drawing the points, I found the lab relatively easy to understand. I could also be mistaken and understood it all wrong though. I understand how it all worked together in the end, or ideally how it was supposed to. I think using this top-down apporach can really help in most programs that requiere you to take some information and manipulate it to print out a specefic type of result.
