[AccessD] Gantt Charts via Access 2007

All,

Our VP of Operations has asked if we could create Gantt charts with Microsoft Access. 

We currently use Access 2007 to create many reports based on data that is stored in our manufacturing system (Firebird Database).

We also employ "Windows Automation" in order to control Excel from Access.

I am curious as to what options are available for the creation of Gantt Charts.

Excel?

Additional software?

Other options?

Thanks,
Brad
