explain the drawing function

[dazwiafl]

maybe we should insert an explanation of the drawing function somewhere on page 2
cause often people wondering why their code isn't doing anything, or they get errors because of the fact that they've deleted the drawing function from the sandbox

Yes, I experienced this, too. In general it is not quite clear what functions are library what belongs to the language and what is browser.

Explaining that drawing() is called automatically and should be used as a start point would help.

Would it be better to rename the function to something like start()?

i like the idea of renaming it to start()

i think it makes it easier to understand that this function is mandatory then the drawing() one....
