+# 🖥️ CPU Scheduling Visualizer (Python + Tkinter)
+
+</div>
+
+A **GUI-based CPU Scheduling Algorithm Visualizer** built using **Python**, **Tkinter**, and **Matplotlib**.  
+It allows users to add custom processes and simulate various scheduling algorithms with **real-time Gantt chart animation**, **ready queue visualization**, and **performance statistics**.
+
+---
+
+## 🚀 Features
+
+✅ Interactive **Tkinter GUI**  
+✅ Supports multiple **CPU scheduling algorithms**  
+✅ Real-time **Gantt chart animation** using Matplotlib  
+✅ Displays **Ready Queue** (for Round Robin & Preemptive algorithms)  
+✅ Shows **average waiting time**, **turnaround time**, and **response time**  
+✅ Add or delete processes dynamically  
+✅ Clean and responsive design  
+
+---
+
+## ⚙️ Supported Algorithms
+
+| Type |                  Algorithm                | Preemptive  | Non-Preemptive |
+|------|-------------------------------------------|-------------|----------------|
+| 🔹   | **First Come First Serve (FCFS)**         |      ❌     |     ✅        |
+| 🔹   | **Shortest Job First (SJF)**              |      ✅     |     ✅        |
+| 🔹   | **Priority Scheduling**                   |      ✅     |     ✅        |
+| 🔹   | **Round Robin (RR)**                      |      ✅     |     ❌        |

+## 🧮 Example Input
+
+| PID | Arrival | Burst | Priority |
+|-----|----------|--------|-----------|
+| P1  | 0        | 5      | 2         |
+| P2  | 1        | 3      | 1         |
+| P3  | 2        | 8      | 3         |
+
+---
+
+## 📊 Output Example
+
+### ➤ Gantt Chart (Animated)
+Displays process execution in timeline order, showing process IDs along the time axis.
+
+### ➤ Results Table
+| PID | Arrival | Burst | Completion | TAT | WT | RT |
+|-----|----------|--------|-------------|------|------|------|
+| P1  | 0 | 5 | 5 | 5 | 0 | 0 |
+| P2  | 1 | 3 | 8 | 7 | 4 | 4 |
+| P3  | 2 | 8 | 16 | 14 | 6 | 6 |
+
+**AVG WT = 3.33 | AVG TAT = 8.67 | AVG RT = 3.33**
+
+---
+
+## 🧠 Working
+
+1. Enter process details (`PID`, `Arrival`, `Burst`, `Priority`)  
+2. Choose your desired **Scheduling Algorithm**
+3. (Optional) Enter Quantum value (for Round Robin)
+4. Click **Run**
+5. Watch the **live animation** of process execution
+6. View detailed results with averages
+

+
+## 🛠️ Tech Stack
+
+- **Python 3.8+**
+- **Tkinter** → GUI Framework  
+- **Matplotlib** → Animation and Gantt Chart  
+- **Threading** → Live simulation without freezing GUI
