My students are working on an assignment of creating a circle graph using the Google Charts in the text box option of the assignment. When they go to submit the assignment with the embed content in the assignment and check their submission, it's someone else's circle graph information. This is the 2nd class that this issue has happen in. I've had about 8-10 students in each class that have submitted their graph the first time and it's been okay. I've had one student re-do the assignment three times and it is still showing someone else's work....HELP!
