Hey, I'm Jeremy - the author of the book in question. I'm happy to say I completely agree, and proudly own two of the book in question! My book's goal was to be a simple read with little overhead in allowing readers to start writing code and see results immediately. Though C is incredibly powerful (goes without saying), many students have a very hard time understanding that C is a language, not a library, and thus has a hard time "outputting" real-time interactive graphics. HTML5 / Canvas, on the other hand, are ready to go without any sort of installation!

Regardless, in my next update I'll be making this point explicitly clear to readers :-) I am not trying to become any sort of tome in the library of great computer-graphics books.
