What is a Gantt Chart?
A Gantt chart is a visual project timeline. Each task appears as a horizontal bar across a calendar — its position shows when the task starts, its length shows how long it takes. Bars can be linked with dependency arrows showing that one task must finish before another begins.
Invented by Henry Gantt around 1910, the Gantt chart has been the standard way to plan any work with multiple moving pieces ever since — software, construction, manufacturing, research, weddings, marketing.
