title: How to draw a graph in LaTeX?
body: <p>First of all, let me say I'm using LyX, though I have no problem using ERT.</p>
  <p>Secondly, what is the most simplest way to draw a simple graph like this in Latex?

  <p>I've seen some documents with graphs and I've seen some examples, but I couldn't figure out how to just draw a simple graph - what packages do I need, etc?</p>
