Gantt chart built using Frappe Gantt (https://frappe.io/gantt, an open-source JavaScript library for Gantt charts). 

Using the chart:

• Switch between Day/ Week/ Month views.
• Hover over a task to see its start and end dates. Click and drag across the chart to select a date range. The bar at the bottom shows the total number of days in the selected range.

First-time setup: Before opening the screen for the first time, run the BootstrapGanttData timer in Service Center to load the sample data.
