The Gantt chart is a specialized chart used for displaying various timelines like project timelines, development timelines etc. It can be used for any of the following:

• Planning and scheduling projects.
• Assessing how long a project should take.
• Laying out the order in which tasks need to be carried out.
• Managing dependencies between tasks.
• Determining the resources needed.

In short, Gantt charts help you monitor progress of a project. You can immediately see what should have been achieved at a point in time. Also, they allow you to judge how remedial action may bring the project back on course, if it's running off the track.
