What app do you use to draw the charts in the book?


I’m interested in the App you have to draw the charts.

The “mind maps” to show the relations between
the objects and how they act to each other.

Can you help?


Aaron has mentioned elsewhere that Omnigraffle was used. Great tool from a software company that makes lots of great Apple software.

The Windows equivalent would be Visio, but using Omnigraffle after using Visio is like walking out of prison for the first time in years. Everything is much brighter, much cleaner.

We do indeed use OmniGraffle for the diagrams in the books. We’re big fans of The Omni Group.


Thank you guys. Will check out Omnigraffle. (Gladly I have a Mac).
