Code = raw LaTeX/TikZ code? If so, I don't really care about that. i just
want the graphic.

When trying C-c C-c after adding this, I get "Symbol's value as variable is
void: latexp" in the minibuffer.

Also, does this assist with my font issue? My main question is how to get
the document font to apply to my babel block. At present, the code shown
above for file_2.org is *perfect* in its behavior (I get a perfectly cropped
PDF of my diagram) except for it not being the right font. I just need to
know to set the font for the TikZ babel output.

Thanks for the assistance,
John
