Bar Graph Software?

Maybe you can help. I need a simple, basic, user friendly app to
create bar graphs. I tried the free app from iTunes, Graph 10.7.9 and
it's not as simple as I would like. Anyone know of a app out there
that may fit my needs? I prefer it be under $100. and geared toward a
desktop platform not iOS. I currently have 10.7.4. Also, I do have
Office 2011, maybe there is something in that bundle? Any help would
be appreciated. Thanks.
