This exercise has students create bar graphs from lists of grades. It is primarily an exercise in functions over list-of-symbols.
Prerequisites: Lists of symbols, Images
Note to Teachers from Providence 2004 Workshop: this is essentially the exercise we did at the workshop.
Thanks to Jordan Johnson from the Providence 2004 workshop for cleaning up the exercises.
I have not yet tried these exercises in v208. If anyone uses them and finds subtleties working with images for the exercise, let me know.
