Algebraic Visualization of Relations Using RelView

摘要

For graphs there exist highly elaborated drawing algorithms. We concentrate here in an analogous way on visualizing relations represented as Boolean matrices as, e.g., in RelView. This means rearranging the matrix appropriately, permuting rows and columns simultaneously or independently as required. In this way, many complex situations may successfully be handled in various application fields. We show how relation algebra and RelView can be combined to solve such tasks.
