The goal of this page is to post interactive graphs that can be used as a classroom resource. Over time, the hope is to add questions that can be used as assignments. In the meantime, consider using these graphs as part of course assignments and let me know if they have been helpful, how to improve them, and what you would like to see. Cheers, Tom
