CSP Unit 3 Lesson 9.6
/* Code generated by RoboBlockly v2.5 */
/* Problem Statement: 
    The pre-placed code uses a repeat loop to draw circles of
    random colors at random locations with a random radius of
    1, 2, or 3 units (and opacity = 50%), on a white
    background. Experiment with the number of iterations to see
    how many it takes to cover the entire background. Compare
    your answer with your neighbor's. (Because of the
    randomness, it will be a little different each time you run
    the code.)
