Alpha Beta NegaMax Visualization tool verification

[delphi_coder]

Hi,
Because of feeling some weakness on understanding Alpha Beta pruning within negamax algorithm I implemented a very simple visualization tool to trace and see its progress visually. There are some visualizer tools for alpha beta pruning in both online and offline form for MiniMax but I couldn't find any for negamax. Wondering if somebody can take a look at this and verify if it works properly. github link: https://github.com/Delphi-Coder/AlphaBetaNegamax-Visualizer
Thanks for time
