Do you mean the “A Picture for Karl’s Students”?

It used to typeset/work but the current manual (for version 3.0.0) has a code on page 45, different from previous version. When I tried just now it didn’t typeset, just as you said.

It is missing one invocation of a library (implicit in the tutorial): insert \usetikzlibrary{intersections} after the \begin{tikzpicture} command finished, so that the beginning of the code should look like:

\begin{tikzpicture}
[scale=3,line cap=round,
% Styles
axes/.style=,
important line/.style={very thick},
information text/.style={rounded corners,fill=red!10,inner sep=1ex}]
\usetikzlibrary{intersections}

% Colors
.
.
.
Then it will work.
