The Dijkstra Path Visualizer is a Java project that combines Test cases and Algorithm library, built with JavaFX visualization. The project follows a clean, modular architecture where input handling, business logic, and presentation stay separated, making it easy to test, extend, and present. It showcases practical Java techniques while producing a working, demo-ready application.
Manual and paper based methods for this task are slow, error-prone, and hard to manage. Without a Java application built on Algorithm library and JavaFX visualization, users cannot process, store, and manage data efficiently, and there is no reliable, reusable way to run the workflow.
This project applies Java techniques through Test cases, orchestrated with JavaFX visualization and Algorithm library. The application is designed for correctness and usability, with clean data flow, validation, and error handling. It produces consistent, reusable results and can be adapted to related tasks with minimal changes.

The project is layered: the input layer handles user interaction through Test cases; the logic layer implements business rules with JavaFX visualization and Algorithm library; and the output layer presents results via Visualization module. Shared validation, storage, and logging modules support all layers, keeping the application robust and easy to extend.
