## Overview

This repository appears to be a JavaFX CPU scheduling simulator, with scheduling algorithms, chart rendering, persistence, and preset-network support represented in the source tree. The README is empty and the only sampled source is the module declaration, so the runtime wiring and detailed behavior cannot be verified; the graph shows the product components without guessing their call relationships.
