If you’ve ever priced out diagramming software, then you know it’s not cheap. The Omni Group’s OmniGraffle starts at $100, and the pro version is twice that.

While it may not be quite as advanced, the Mac App Store title will fit the needs of a lot of users looking to do mind maps and other diagrams.
