title: How do I align 3 dataframes diagonally in a larger dataframe such that the remaining values are empty
body: <p>I have 3 dataframes that hold numbers from 1 to 9. I want to create a larger dataframe that consists of these 3 dataframes aligned diagonally. The dataframes are as below.</p>
  <pre><code>df_gr1 = pd.DataFrame(data=[[5, 4, 7], [1, 9, 6], [2, 8, 3]])
  df_gr2 = pd.DataFrame(data=[[3, 2, 7], [5, 1, 8], [4, 9, 6]])
  df_gr3 = pd.DataFrame(data=[[2, 3, 9], [8, 5, 6], [7, 1, 4]])
  </code></pre>
  <p><code>display(df_gr1)</code>  Output-&gt; <a href="https://i.stack.imgur.com/NHgvv.png" rel="nofollow noreferrer">df_gr1</a></p>
  <p><code>display(df_gr2)</code>  Output-&gt; <a href="https://i.stack.imgur.com/IFJpb.png" rel="nofollow noreferrer">df_gr2</a></p>
  <p><code>display(df_gr3)</code>  Output-&gt; <a href="https://i.stack.imgur.com/hM1ab.png" rel="nofollow noreferrer">df_gr3</a></p>
  <p>The Final DataFrame that I am looking for is something like this:</p>

  <p>I plan to append values to the empty cells <strong>after</strong> this dataframe is created. But first I need it to be empty.</p>
  <p>Hoping for something dynamic.</p>
  <p>Thank You</p>
