Software to create diagramatic Tech Trees?

[sickre]

I was wondering if anyone could suggestion software that can create diagramatic Tech Trees (Like the one you see here http://www.civfanatics.com/civ4/techtree/ )

I guess some kind of flowchart program would work best, I'm just looking for suggestions as to which one.

I'm planning on creating a greatly expanded tech tree for CivIV.

Thanks.

Wrong forum, all questions go in the main C&C forum.
