In recent years, many systems for visualizing and exploring massive amounts of data have emerged. A topic that has not yet been investigated much concerns the visualization and exploration of constraints between objects such as relationships of joint contribution to a set or mutual exclusion. In this paper, we present concepts toward visualizing mutual constraints in the well-known game of Sudoku -- a member of the group of np-complete exact set covering problems. In the context of our work, the game is used as a case study to visualize interactions between humans and computers in which the computer is an assistant to users, supporting them in understanding the problem rather than automatically providing the final solution.     «
