Vaadin flexible gantt diagram:

• Tasks treetable
• Customizable table
• Column formatter
• Customizable task representation
• Completion percent
• Tasks dependencies
• Customizable scale (year, month, day, hour)
• Milestones at diagram
• Tasks filtering

• You also should add link to repository and dependencies to project's pom.xml

• This version doesn' t use vaadin Container interface. It uses GanttDiagramModel instead. At first you should describe model and then call diagram setModel() method.
