Just to add to Ryans words...
If you want to avoid 3rd party modules, take a look at turtle and the
Tkinter *Canvas* widget in the standard library. Here is an example.

#-- start code --#
try:
    import Tkinter as tk
except ImportError:
    import tkinter as tk #python 3+

app = tk.Tk()
canvas = tk.Canvas(app)
canvas.create_line(0,0, 50,50, arrow='last')
canvas.pack()
app.mainloop()
#-- end code --#

remove the try/except when you know which one to use. I just wanted to
make sure it ran out-the-box for you, have fun!
