A typical Gantt Chart looks like this:

Tasks        | Time →
Requirement  | ████
Design       |     █████
Coding       |          ███████
Testing      |                 ████

👉 Each bar shows:

• Start time
• End time
• Duration

---

🔹 5. Key Features

• Shows start and end dates of tasks
• Displays overlapping activities
• Tracks progress of each activity
• Easy to understand visually
