Newb question re: "Visualizing Data" pp.

Why do the lines

 PFont font = loadFont("AgencyFB-Reg-12.vlw");
 textFont(font);

have to come at the very beginning of the setup() block? I originally added them after size(), and the sketch did not work properly.

You don't, there's just a current bug that has been around for a while but for some reason has become far more prevalent in recent months:
http://dev.processing.org/bugs/show_bug.cgi?id=726
The problem is that textFont(), when used inside setup(), is sometimes forgotten by the time that draw() runs.

The size() command should *always* be at the beginning of setup(), and loadFont() can happen any time after that (preferably inside setup(), so you aren't re-loading the font at 60 frames a second).

To get around the bug, you'll need to use textFont(font) inside draw() (or before you use text). This particular bit will be fixed in an upcoming release.
