An Odoo Gantt View app is generally used in project management as it helps in showing various activities (events/tasks) displayed against time through the Gantt chart. On the left side of the view app is a list of the specific activities, and along the top is a suitable time scale in the Gantt view. Every activity is represented by a bar; the bar's length and position show the start date, time period, and end date of that activity in the Gantt Chart Odoo.
