Example problem
---

Write a program, analyze_dist.py, that reads the data from the file 
muzny_distances.txt and graphs it accordingly on a scatter plot.

Use a constant to save the file name.

Update the program to plot all points simultaneously.


Update the program to plot the strange_distances.txt in a separate series.
Add a legend.
