body: <p>I am trying to create a 2x2 plots for Anscombe data-set</p>
  
  <p><strong>Loading Data-set and separating each class in data-set</strong></p>
  
  <pre><code>import seaborn as sns

  dataset_2 = anscombe[anscombe['dataset'] == 'II']
  dataset_3 = anscombe[anscombe['dataset'] == 'III']
  dataset_4 = anscombe[anscombe['dataset'] == 'IV']
  </code></pre>
  
  <p><strong>Creating a figure and dividing into 4 parts</strong></p>
