title: How to export every TikZ image to a separate pdf file?
body: <p>I'm creating some graphs for my thesis in a single <code>.tex</code> file using the TikZ package in LaTeX.<br>
  I'm using the standalone document class so that my graphs are generated without whitespaces. </p>
  
  <p>How can I export every graph in a separate PDF file so I can load them individually in another project?  </p>
