Dynamic Organizational Chart Generation Software?

MrEfficient asks: "I'm searching for an Oranizational Chart software package that stores employee data in a database. Ideally, it would be web based, or if not, at least allow client programs to access a remote database over an intranet or the internet. It can be either Linux or Windows based. All the software I've seen is little more than a drawing program which allows one to manually create a visual chart but with no way to manage the data behind it (OrgPlus is the one I've been using). This is fine when your company has less than twenty people, but completely inadequate when the company size is in the thousands. The lack of a database-backed organizational chart program is strange when you consider that the organizational chart is the most common example used when discussing trees in SQL. I've considered Kivio, a flowchart program for KDE, which isn't designed for organizational charts but looks like it could serve as one given its scriptablity. So, what do you think, does anyone have any suggestions?"
