What is a 'Gantt chart' used for in project management?

A Gantt chart is a visual tool used in project management to represent the timeline of a project. It illustrates the start and finish dates of various elements of the project, making it easy to see how tasks overlap and how long each task is expected to take. This visualization helps project managers to track progress against deadlines and ensure that the project remains on schedule. By providing a clear overview of tasks, dependencies, and milestones, a Gantt chart enhances communication among team members and stakeholders regarding the project's progression.

The other options, while relevant to project management, do not accurately describe the primary function of a Gantt chart. Resource allocation, budget creation, and stakeholder analysis involve different types of tools and methodologies that focus on specific aspects of project management rather than the overall scheduling and tracking of project tasks.
