Line width of plotted data in \tikz \datavisualization

Question

Does anybody know how to set line-width of plotted data using command data[]{} in the command \tikz \datavisualization?

Answer 1

Slightly modifying an example from section 78.2.3 Styling a Visualizer in the manual:

\documentclass{standalone}
\usepackage{tikz}
\usetikzlibrary{datavisualization,datavisualization.formats.functions}
\begin{document}
\tikz \datavisualization
[scientific axes=clean,
visualize as smooth line/.list={sin},
sin={style={red,line width=4pt}} %%% <--- style of lines in sin set defined here
]

data [set=sin, format=function] {
var x : interval[0:3*pi];
func y = sin(\value x r);
};
\end{document}
