What does a Gantt chart primarily illustrate?

A Gantt chart is a visual project management tool that primarily illustrates project tasks over time. It provides a chronological overview of the various tasks involved in a project, displaying their start and end dates, durations, and how they overlap with one another. This visual representation allows project managers and team members to easily track progress, identify dependencies between tasks, and assess the overall timeline of the project.

By arranging tasks along a timeline, a Gantt chart helps in planning and scheduling, ensuring that all project activities are aligned with the project's objectives and deadlines. It is particularly useful for monitoring the work in progress and facilitating communication among team members about task completion and project milestones. This clarity in task management is what makes a Gantt chart an essential tool in project planning and execution.
