+# Write your entire commit message above this line.
+# 
+# The first line should be a quick description of what you changed.
+# Then leave a blank line. 
+# Then, taking as many lines as you want, answer the questions for 
+# your current checkpoint: 
+#
+# Checkpoint 1: How much of the scatter plot do you think you could 
+# write on your own right now? While you were planning, did you come 
+# across any specific issues which you would not know how to program 
+# yet?
+#
+# Checkpoint 2: In this checkpoint, you were asked to write some more
+# complex functions than you may have written before. How did it go? 
+# Did it feel like a different kind of thinking? When you got stuck, 
+# what strategies did you use to make progress?
+#
+# Checkpoint 3: This may have been the most complex program you have
+# yet written. How did it go? Did you understand how the parts came 
+# together? Compare the top-down thinking you did in Checkpoint 1 with 
+# the way this lab broke down the scatter plot program. Did you have 
+# any ideas for other programs you could write?
