title: Matplotlib: Plot countplot for two or more column on single plot
body: <p>My dataFrame, df:</p>
  
  <pre><code>Sno | Attribute_1   | Attribute_2   | Attribute_3
  __________________________________________________
  1   | option_1      | option_3      |option_2
  2   | option_1      | option_1      |option_1
  3   | option_2      | option_2      |option_2
  4   | option_1      | option_1      |option_3
  5   | option_3      | option_2      |option_2
  6   | option_3      | option_3      |option_1
  7   | option_1      | option_3      |option_2
  </code></pre>
  
  <p>Here Attribute_1, Attribute_2 and Attribute_3 contains categorical data - option_1 or option_2 or option_3 for each of the rows.</p>
  
  <p>I want to create a count plot on the same plot for all the attributes.
  I am able to do it for one column by:</p>
  
  <pre><code>sns.countplot(x="Attribute_1", data=df);
  </code></pre>
  
  <p>I can individually create for each of the attributes, but what I am looking for it that on the same plot I can have count plot for all the attributes.
  i.e X-axis will have attributes, and each attribute will have three count plot.</p>
