What is a Gantt chart

A Gantt chart is a bar chart used for project planning and schedule management. It shows tasks, durations, execution order and completion status along a timeline. Gantt charts help project teams plan resource allocation, track task progress and manage project milestones. They are widely used in software development, engineering management and project collaboration.
