A Gantt chart is primarily used as a visual representation of a project timeline. It typically displays the start and finish dates of the various elements of a project, allowing for an easy comparison of planned versus actual progress. The chart illustrates the relationship between tasks and how they align in time, effectively showing the amount of work done or production completed over a specified duration. This is invaluable in project management as it helps teams monitor progress, identify delays, and adjust schedules as needed.

The other options reflect different aspects of project management but do not capture the primary purpose of a Gantt chart. While a project’s overall budget is critical, it does not pertain to the visual timeline aspect of project tasks. Similarly, tracking the number of employees on a project relates to resource management but is not represented in a Gantt chart. Lastly, marketing strategies pertain to a project's external promotion and are not depicted through a Gantt chart, which focuses instead on internal timelines and task management.
