Visual representations of maze within a grid with colors encoding different criterias. May show walls overflooded to emphasize the structure of the maze and reduce visual noise.

By default, the cell path is in green whereas cells in blue are the one stored in memory (waiting to be processed).
Color gradient encodes the Manhattan distance from the starting cell when used by maze generator algorithms. It is useful to compare the structure of mazes visually; without color, the black and white alternating cells are too noisy to offer any pre-attentive comparisons.
