Created for use with a specific mobile game in mind, GridMap allows you to visualize the spread of entities for any coordinate grid type map. The inspiration to create this Java desktop application comes from the difficulty of finding reward nodes that are spread out and hard to find. Within this mobile game, there are titan mobs that, when killed, randomly throw out a certain number of reward nodes on the map. Utilizing this program, I was able visualize the spread and determine an easier way of finding the reward nodes.
