\tikzstyle{io} = [fill=farbe,inner sep=15pt,circle]
\begin{document}
\begin{tikzpicture}
\node[io] (a) {};
\node[io,below=2 of a] (b) {};
\node[io,right=2 of b,yshift=.5cm] (c) {};
\draw (a) -- (b) -- (c);
\path (a) -- (b) node[rotate=180,midway,sloped,below=3] {\large SOMETHING TEXTY};
\end{tikzpicture}
\end{document}
输出如下:
