Though not related to data analysis or visualization, the very basic Tic-Tac-Toe game I made while leaning was my favorite project so far. My kids and I have have had so much fun playing and enjoyed watching them go from losses to wins and then constantly to ties as they learnt the rules, applied them, and kept track of them. When, I have a chance in the future, I plan to return to this project to retrieve inputs, create profiles, keep historical track of scores, have a better user interface, and add sounds for the kids.
