The Problem

Reproducing an example from the pgf manual appears to work, yet reports an error. Does anyone have a guess what the problem is?

MWE

\documentclass{minimal}

\usepackage{tikz}
    \usetikzlibrary{datavisualization.formats.functions}


\begin{document}
    \begin{tikzpicture}
        \datavisualization [school book axes, all axes={unit length=5mm, ticks={step=2}}, visualize as smooth line]
        data [format=function] {
        var t : interval [0:2*pi];
        func x = \value t * cos(\value t r);
        func y = \value t * sin(\value t r);
        };
    \end{tikzpicture}


\end{document}

Detail of Error(s)

! Undefined control sequence. \pgfutil@font@footnotesize
->\footnotesize 
                                            l.13  };

and repeated instances of

The control sequence at the end of the top line of your error message
was never \def'ed. If you have misspelled it (e.g., `\hobx'), type `I'
and the correct spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.

Systems Tested

Tested on Overleaf and Linux TexStudio. Both are running PDFLaTeX.

The problem comes from the fact that theminimalclass doesn’t define size changing commands such as \footnotesize, just use article instead.

This is one of the reasons why minimal in general should be avoided, see Why should the minimal class be avoided?
