We will be moving all homework questions to an online forum. Go to: https://groups.google.com/a/cs.usfca.edu/d/forum/datavis Login with your USF Connect username and password. All homework questions sent via email will be redirected to these forums. (You can also click the "Forum" link on the course website.) Please do not include full solutions! Code snippets are okay. Make sure you search to see if your question as already been answered before posting.
Update: There is an issue with the @dons.usfca.edu accounts preventing students from accessing these forums. I have submitted a ticket, but in the meantime will find a different solution for questions.
