Yes the link didn't have the simple examples I hoped for.  How's this:
-----------------------------
import pygame
import time

pygame.init()
screen = pygame.display.set_mode((1024, 768) )
red = (255,0,0)
green = (0,255,0)

screen.fill( (255,255,255) )
pygame.draw.lines(screen, red, False, ((0,0),(100,100)))
pygame.draw.lines(screen, green, False, ((0,100),(100,0)))
pygame.display.update()

time.sleep(5)
pygame.quit()
------------------------------

PyGame has other primitives like circles, ellipses, etc.  Much like the
old BASIC graphics primitives.

Yes I think it can.

Are you thinking of sprites?

This is sort of similar to PyGame's concepts.
