I'm looking for a tool to use with my advisees that will allow each of them individually to rank themselves and the group on a scatterplot-like graph ("On indicator X, I believe that I am putting in ... effort, while I believe that the rest of the group is putting in ... effort" with student effort on the X axis and group effort on the Y axis, for example), AND then, after indicating their placement, combining all of the dots to a whole group scatterplot for discussion.  Do I have to use paper?  Ideas? 

Thank you!
