title: Rounded boxes with text inside in beamer
body: <p>I want to have several texts in latex which are boxed in a circle or more in a rounded box.
  I tried to use:</p>
  
  <pre><code>\pgfnodecircle{Node1}[stroke]{\pgfxy(1,1)}{0.5cm}
  \pgfnodecircle{Node2}[strokel]{\pgfxy(3,0.5)}{0.25cm}
  \pgfnodecircle{Node3}[fill]{\pgfxy(5,1)}{0.25cm}  
  \pgfnodeconnline{Node1}{Node2}  
  \pgfnodeconnline{Node2}{Node3}
  </code></pre>
  
  <p>but this <code>\pgfnodecircle</code> command does not allow me to write text inside the nodecircle.
  I could have added text with <code>\pgfnodebox</code> but I really want the text to be surrounded by rounded boxes and not by rectangular boxes.</p>
