title: How to properly set-up Graphviz for Polars on Mac or Windows?
body: <p>Polars has a powerful feature called <code>df.show_graph(optimized=True)</code>.</p>
  <p>Have been trying to get this installed on my Windows and Mac computer, system info is below.</p>
  <p><strong>Windows</strong><br />
  OS = Windows 10<br />
  Architecture = x86_64</p>
  <p><strong>MacBook</strong><br />
  OS = Monterey<br />
  Arch= arm64 (Apple Sillicon M1 Mac)</p>
  <hr />
  <p>Have installed <code>polars==0.13.40</code> and installed <code>graphviz==0.20</code>, including matplotlib. Additionally, have added GraphViz and Matplotlib (site-packages) to the PATH environment variable; but still, receive the below error message.</p>
  <pre><code>ImportError: Graphviz dot binary should be on your PATH and matplotlib should be installed to show graph.
  </code></pre>
  <p>Could someone please share a simple guide on how to set up Graphviz for Polars via Windows 10 or MacBook (with Apple Sillicon)?</p>
  <p>Thanks
