The world today is inundated with data that communicate important mathematical ideas in a variety of representational forms. These different representations fundamentally affect how people interpret and use those ideas. However, graphical representations of data are no longer the typical static representations taught in secondary classrooms. Technological advances have given rise to nontraditional, multidimensional graphical representations that could not be displayed on a twodimensional sheet of paper.
