You can easily share information visually with this free Gantt chart maker. Gantt charts are useful when planning out a large project because they allow the project to be broken down into manageable chunks and laid out in a timeline. A horizontal line on the opposite side of the chart represents the duration of each task. This task mapping makes it easy to assess the relative durations of individual steps and identify areas of duplication. Project managers often find it helpful to have a visual representation of their plans and schedules in the form of a Gantt chart, which can show things like the order in which tasks will be completed, the deadlines for those tasks, and the relationships between different projects and their respective managers.
