1. Read the code and Predict what you think you will see when you run the program.

2. Run the program and see if your prediction was correct.

3. Investigate why the program works. Explore any questions OR your own:

What is shrinkFactor doing? What if you doubled or halved it?
Look at the variable i in the for-loop on line 9. Does it have to be called i? If you change it, what else do you have to change?
Look at the array on line 1. What happens if you add another comma and a number? Are the square brackets necessary?

4. Modify the code to build your understanding. Complete these tasks in order:

Make the circles line up in the center of the canvas.
Add a new array to hold one color word for each circle. var cols = ["red", "yellow", "lightgreen", "blue]; Change line 12 to use the colors from the new array.
Add a new array to hold the years for each data point. Display the years as text under each circle.
