3.5 stars rounded down. Relatively easy read; if you're completely new to these concepts, it presents them in an easy-to-understand manner. If you're already familiar with them, it serves as an easygoing "back-t0-basics" style.

Yes, there are plenty of charts and graphs - there's no escaping those! But there's also plenty of wit and a healthy mix of examples both outrageous and practical that make for a good time reading.
