Which planning tool gives a graphical representation of project tasks over time?

A Gantt chart serves as a visual planning tool that illustrates project tasks plotted against time, providing a clear timeline for each task involved in a project. It showcases starting and ending dates for various tasks, making it easy to see how tasks overlap and the overall project schedule. Users can quickly assess which tasks are in progress, which are completed, and any delays that may affect the project's timeline.

In contrast, other tools like network diagrams focus on the relationships and dependencies between tasks but do not provide a chronological graphical representation. Flowcharts depict processes and decision points but do not specifically represent tasks over time. PERT charts also structure tasks concerning time and dependencies but are generally more complex and do not provide the straightforward timeline visualization that Gantt charts do. Each of these tools serves specific functions in project management, but for a direct visual correspondence between tasks and their timeframes, a Gantt chart is the most effective choice.
